Academic literature on the topic 'Trees in cities – Ontario – Toronto'

Effective management of the urban forest calls for municipalities to have a tree inventory of their urban resource. The approach to urban forestry is rather different in Europe and North America, both in terms of background and culture. This contribution discusses similarities and differences in tree inventory practices, based on a pilot study of three major cities in North America (Toronto, Ontario, Canada; and Boston, Massachusetts and New York City, New York, U.S.) and three major cities in Northern Europe (Oslo, Norway; and Aarhus and Copenhagen, Denmark). The pilot study consisted of semi-structured expert interviews in each city, and an analysis of their tree inventories in terms of their level of detail, how they were undertaken, and how they have been used. Each of the cities, with exception of Oslo, had inventoried all of their street trees. Volunteers were only used in Boston and New York City. None of the cities had developed a management plan based on their tree inventory. The inventory had only been completely incorporated into the work order system in New York City and Toronto. This explorative study shows that more research is needed to investigate what subsequently happens to tree inventories in municipalities after they have been performed. Moreover, more work is needed to identify whether inventories are being utilized to their full advantage in terms of producing management plans. Some key themes for further research are described. The set up of this pilot study could serve as a format for comprehensive research.

The arrival and establishment of adventive, invasive forest insects are a threat to the health, diversity, and productivity of forests in Canada and the world at large, and their early detection is essential for successful eradication and management. For that reason, the Canadian Food Inspection Agency (CFIA) conducts annual surveys at high risk sites such as international ports and freight terminals, industrial zones, and disposal sites for solid wood packaging material using two methods: (1) semiochemical-baited traps deployed in a total of about 63–80 sites per year in British Columbia (BC), Ontario (ON), Quebec (QC), New Brunswick (NB), Nova Scotia (NS), and Newfoundland and Labrador (NL); and (2) rearing of insects from bolts collected from stressed trees and incubated in modified shipping containers in four cities (Vancouver, Toronto, Montreal, and Halifax). We report 31 new Canadian provincial records of Coleoptera from surveys conducted in 2011–2021, including 13 new records for Canada and 9 species adventive to North America (indicated by †). Nine of the new Canadian records were native North American species previously detected only south of the border. All but three species belong to the Curculionidae family and most of these were in the subfamily Scolytinae. The records include: Xenomelanophila miranda (LeConte) (Canada, BC) (Buprestidae: Buprestinae); Neoclytus mucronatus mucronatus (Fabricius) (BC) (Cerambycidae: Cerambycinae); Amphicerus cornutus (Pallas) (Canada, BC) (Bostrichidae: Bostrichinae); Mecinus janthinus (Germar)† (ON) (Curculionidae: Curculioninae); Aulacobaris lepidii (Germar)† (Canada, ON); Buchananius striatus (LeConte) (ON) (Curculionidae: Baridinae); Cylindrocopturus binotatus LeConte (Canada, ON) (Curculionidae: Conoderinae); Himatium errans LeConte (ON); Phloeophagus canadensis Van Dyke (ON); Rhyncolus spretus Casey (Canada, BC); Stenomimus pallidus (Boheman) (Canada, ON); Tomolips quercicola (Boheman) (Canada, ON) (Curculionidae: Cossoninae); Strophosoma melanogrammum (Forster)† (NB) (Curculionidae: Entiminae); Conotrachelus aratus (Germar) (ON) (Curculionidae: Molytinae); Anisandrus maiche Stark† (Canada, ON, QC); Cnesinus strigicollis LeConte (Canada, ON); Cyclorhipidion pelliculosum (Eichhoff)† (Canada, ON, QC); Hylesinus fasciatus LeConte (QC); Hylesinus pruinosus Eichhoff (QC); Hypothenemus interstitialis (Hopkins) (Canada, ON); Lymantor alaskanus Wood (BC); Pityogenes bidentatus (Herbst)† (Canada, ON); Scolytus mali (Bechstein)† (BC); Scolytus schevyrewi Semenov† (QC); Trypodendron scabricollis (LeConte) (Canada, ON); Trypophloeus populi Hopkins (QC); Xylechinus americanus Blackman (NFLB); and Xylosandrus crassiusculus (Motschulsky)† (BC, QC) (Curculionidae: Scolytinae). We also provide additional data confirming the presence of the adventive Hylastes opacus Erichson† in NS. Rearing of insects from bolts accounted for two new records (H. pruinosus, R. spretus) and trapping accounted for the remainder. These surveys not only assist our efforts to manage forest insects by documenting new species introductions and apparent range expansions but also increase our knowledge of biodiversity.

The beech scale insect, Cryptococcus fagisuga was found on American beech trees, Fagus grandifolia for the first time in Ontario in 1981. The affected trees were located in the Newmarket area north of Toronto.

Purpose This paper aims to present a panel data econometric model of the main determinants of house prices in the ten largest census metropolitan areas (CMA) in Ontario, Canada, for the years 2001, 2006 and 2011. The impact of immigration on the housing market in Canada is little researched; however, immigration plays an important role into the economy of Canada. According to Statistics Canada, not only is immigration key to Canada’s population growth but also without immigration, in the next 20 years, Canada’s population growth will be zero. The motivation for this study is the bursting of housing bubbles in some developed countries (e.g. USA). The authors analyze variables that are related to the immigration policy in Canada, accounting also for the impact of the interest rate, income, unemployment, household size and housing supply to analyze housing price determinants. The study investigates the magnitude of the impact of the top three leading categories of immigrants to Canada, namely, Chinese, Indian and Filipino, on the housing prices in Ontario’s largest cities. The results show the main factors that explain home prices over time that are interest rate, immigration, unemployment rate, household size and income. Over the 10-year period from 2001 to 2011, immigration grew by 400 per cent in Toronto CMA, the largest receiving area in Ontario, while the nonimmigrant population grew by 14 per cent. For Toronto CMA, immigrants, income, unemployment rate and interest rate explain the CA$158,875 average home price increase over the 2001-2011 time period. Out of this, the three categories of immigrants’ share of total home price increase is 54.57 per cent, with the corresponding interest rate share 58.60 per cent and income share 11.32 per cent of the total price growth. Unemployment rate contributes negatively to the housing price and its share of the total price increase is 24.49 per cent. Design/methodology/approach The framework for the empirical analysis applies the hedonic pricing model theory to housing sales prices for the ten largest CMAs in Ontario over the years 2001-2011. Following Akbari and Aydede (2012) and O’Meara (2015), market clearing in the housing market results in the housing price as a function of several housing attributes. The authors selected the housing attributes based on data availability for the Canadian Census years of 2001, 2006 and 2011 and the variables that have been most used in the literature. The model has the average housing prices as the dependent variable, and the independent variables are: immigrants per dwelling (Chinese, Indian, and Filipino), unemployment rate, average employment income, household size, housing supply and the interest rate. To capture the relative scarcity of dwellings, the independent variable immigrants per dwelling was used. Findings This study seems to suggest that one cause of high prices in Ontario is large inflows of immigrants together with low mortgage interest rate. The authors focused their attention on Toronto CMA, as it is the main destination of immigrants and comprises the largest cities, including Toronto, Mississauga, Brampton and Oakville. Looking over the 10-year period from 2001 to 2011, the authors can see the factors that impact the home prices in Toronto CMA: immigration, unemployment rate, household size, interest rate and income. Over the period of 10 years from 2001 to 2011, immigrants’ group from China, India and the Philippines account for CA$86,701 increase in the home price (54.57 per cent share of the total increase). Income accounts for CA$17,986 increase in the home price (11.32 per cent share); interest rate accounts for CA$93,103 of the average home price increase in Toronto CMA (58.60 per cent share); and unemployment rate accounts for CA$38,916 decrease in the Toronto average home prices (24.49 per cent share). Household size remain stable over time in Toronto (2.8 average household size) and does not have a contribution to home price change. All these four factors, interest rate, immigrants, unemployment rate and income, together explain CA$158,875 increase in home prices in Toronto CMA between 2001 and 2011. Practical implications The housing market price analysis may be more complex, and there may be factors impacting the housing prices extending beyond immigration, interest rate, income and household size. Finally, the results of this paper can be extended to include the most recent census data for the year 2016 to reflect more accurately the price situation in the housing market for Ontario cities. Social implications The fact that currently, in 2017, the young working population cannot afford buying a property in the Toronto CMA area means there is a problem with this market and a corresponding decrease in the quality of life. According to The Globe and Mail (July 2017), a new pool in 2017 suggested that two in five Canadians believe housing in this country is not affordable for them. Further, 38 per cent of respondents who consider themselves middle or upper class believe in no affordability of housing. The Trudeau Government promised Canadians a national housing strategy for affordable housing. Designing a national housing strategy may be challenging because it has to account for the differential income ranges across regions. Municipal leaders are asking the government to prioritize repair and construct new affordable housing. Another reason discussed in the media of the unaffordability of housing in Toronto and Vancouver is foreign buyers. The Canadian Government recently implemented a tax measure on what it may seem the housing bubble problem: foreign buyers. Following Vancouver, in April 2017, Ontario Government imposed a 15 per cent tax on foreign buyers who are not Canadian citizens or permanent residents. This tax is levied on houses purchased in the area stretching from Niagara Region and Greater Toronto to Peterborough. Originality/value Few studies use Canadian data to explain house prices and analyze the effect of immigration on housing prices. There is not much research on the effect of the immigrants and immigrants’ ethnicity (e.g., Chinese, Indian and Filipino immigrants), on the housing prices in Canada cities. This study investigates the impact of the most prevalent immigrant races (e.g., from China, India and the Philippines) on housing prices, using data for Canadian major cities in Ontario within a panel data econometric framework. This paper fills this gap and contributes to the literature, which analyzes the determinants of housing prices based on a panel of cities in the Canadian province of Ontario.

Toronto, in the province of Ontario, Canada was one of the cities severely impacted by Severe Acute RespiratorySyndrome (SARS). SARS required the health care system to respond quickly and efficiently. This paper describes thesituation and response at a large public academic aged care centre.

This paper examines the political intersection of religion and education in Ontario, Canada, from1840 to 2011. Currently, Ontario is Canada’s most ethno culturally diverse province, and Toronto, its capital city, is one of the most multicultural cities in the world. The issue of public funding of religious education in Ontario has emerged at varying times in the province’s history. In particular, selective Ontario provincial election campaigns are discussed in relation to exploring the degree to which public funding of religious education and religious accommodation emerged as political issues. Social mobilization theory provides a rich and varied conceptual lens through which to examine decisions that have led to the current place of state funding of religious education in Ontario.

The AAAI-12 Workshop program was held Sunday and Monday, July 22–23, 2012 at the Sheraton Centre Toronto Hotel in Toronto, Ontario, Canada. The AAAI-12 workshop program included 9 workshops covering a wide range of topics in artificial intelligence. The titles of the workshops were Activity Context Representation: Techniques and Languages, AI for Data Center Management and Cloud Computing, Cognitive Robotics, Grounding Language for Physical Systems, Human Computation, Intelligent Techniques for Web Personalization and Recommendation, Multiagent Pathfinding, Neural-Symbolic Learning and Reasoning, Problem Solving Using Classical Planners, Semantic Cities. This article presents short summaries of those events.

The interurban network of criminal collaboration in Canada is described, and possible explanations for its structure are explored. The data include all police-reported co-offences in the 32 major cities of Canada during 2006–09. Component analysis and graph drawings in network space and in geospace elucidate the structure of the network. Quadratic assignment procedure multiple regressions, repeated separately on the networks of instrumental and noninstrumental co-offences, test hypotheses about possible determinants of the network structure. The cities form one connected component, containing two clusters connected by a link between Toronto and Vancouver. One cluster, centred on the triad of Toronto, Montreal, and Ottawa, comprises the cities in Ontario and Quebec, with weak links to cities in the Atlantic provinces. The other cluster, centred on Vancouver, comprises the cities in the four western provinces. The structure is strongly correlated with the residential mobility of the general population, which in turn is strongly correlated with intercity distances. The correlation with mobility is less strong for instrumental than for noninstrumental crimes. The structure of this co-offending network can be explained by criminals’ routine activities, namely ordinary residential mobility, but the alternative explanation of purposive interurban criminal collaboration is more plausible for instrumental crime.

The reuse of brownfields as locations for urban intensification has become a core strategy in government sustainability efforts aimed at remediating pollution, curbing sprawl and prioritizing renewal, regeneration, and retrofitting. In Ontario, Canada’s most populous, industrialized, and brownfield-laden province, a suite of progressive policies and programs have been introduced to not only facilitate the assessment and remediation of the brownfields supply, but to also steer development demand away from peripheral greenfields and towards urban brownfields in a manner that considers a wider regional perspective. This article examines the character and extent of brownfields infill development that has taken place in three Ontario cities (Toronto, Waterloo, and Kingston) since the provincial policy shift in the early 2000s. Using property assessment data and cleanup records, the research finds that redevelopment activity has been extensive in both scale and character, particularly in Toronto where the real estate market has been strong. While the results are promising in terms of government efforts to promote smarter growth that builds “in and up” instead of out, they also reveal that government could be doing more to facilitate redevelopment and influence its sustainability character, particularly in weaker markets.

During the first great burst of urban growth in Canada from the beginning of the 20th century and on into the 1920s it was generally the municipalities, either singly or collectively, which fostered policy innovation and new services. Provinces generally did little at that time, either to foster new policies or rein in local autonomy. It was only after the economic setbacks of the depression and a renewed spirit of urban development after 1945 that provincial direction over municipalities became much more significant. This paper is a case study of two major policy crises which threatened the viability of the whole municipal system in Ontario. In the 1930s the Border Cities (Metropolitan Windsor) faced bankruptcy and economic collapse and placed in jeopardy the credit of the province. In the early 1950s the inability of Metropolitan Toronto to create area-wide solutions to severe servicing problems threatened to stall the main engine of provincial growth. The case study demonstrates how a reluctant provincial government intervened to create new metropolitan arrangements for the two areas and accompanied this with a greatly expanded structure of provincial oversight including a strengthened Ontario Municipal Board and a specific department to handle municipal affairs. The objective of the policy was to bolster local government rather than to narrow municipal autonomy.

Research on house prices and housing markets has traditionally been concerned with the modelling of house price determinants using hedonic regression equations and other methods of data interpretation. While this research has unveiled some useful insights into the relationships between housing supply, housing demand, and selling price, more recent work has focused on the "specialness" of housing as a commodity and the subsequent dismissal of regression techniques that only serve to throw us into a "statistical soup". Recent research is different in two key respects. First, forces other than macro-level variables (eg. interest rates and the availability of finance) and micro-level variables (household income, size, proximity to work) are believed to contribute to the fluctuations in housing prices over time and through space: specifically, more subjective evaluations of locational amenity, identity construction, and community are now considered in the valorisation of housing. Furthermore, newer research also understands that exogenous influences (eg. immigration, foreign investment) now play a key role in the determination of residential value. This research on residential real estate markets in Canada engages in discussions revolving around the latter of the two approaches using both qualitative and quantitative methods. At the inter-urban scale, analysis of house price movements in Canada's largest cities shows the divergence of Toronto and Vancouver from other CMAs, a trend that coincides with the increasing globalisation of both cities over the last 15 years. Further, intra-urban analyses of both Toronto and Vancouver demonstrate differential impacts of globalisation and economic restructuring within each city with particular neighbourhoods being placed on more of a "global" real estate market (eg. gentrified neighbourhoods, residential areas experiencing offshore investment, and areas of settlement for wealthy immigrants). The particular impacts of globalisation are, however, very different in each city and is dependant upon the nature of the global flows that converge there. Moreover, these results are not politically mute; considerable effort has been expended in Vancouver at least to obscure the actual effects of internationalisation on the regional housing market.

This chapter compares Buffalo, New York, and Toronto, Ontario, two urban areas located on the Great Lakes with similar populations (one million) in 1950. Toronto has since passed the six million mark, while Buffalo seems trapped in a seemingly irreversible cycle of economic decline. The diverging destiny of the two cities has many roots (e.g., the St. Lawrence Seaway, the collapse of Big Steel) but invariably sends us back to the different political cultures of the United States and Canada. The government of Ontario stepped in early in the urbanization process to impose a model of metropolitan governance on the Toronto region, with the explicit aim of deterring the emergence of deep social divides, specifically between city and suburb, and ensuring the maintenance of a strong central core. The state of New York did no such thing in Buffalo, for which Buffalo continues to pay a price.

As smart technologies become more integrated with daily life, vital digital literacy skills are necessary for citizens to engage with and benefit from their cities, local government, and economy. Libraries play an important role in mitigating the growing wealth gap in our communities, especially as it relates to opportunities provided by emerging technologies. With the call for smart city proposals in Toronto, Ontario, what role will the city's LAMs have in collaborating with these future developments? The Toronto Public Library (TPL), a trusted public institution, has a stake in implementing various frameworks and collaborating with government agencies in addressing public concerns around technologies that collect personal information for various purposes and ensuring that vulnerable populations are not left behind. Following an examination of the role libraries play in mitigating consequences of the digital divide, this chapter will discuss the various ways in which TPL and similar community libraries have been involved with digital literacy and inclusion. It will also explore how TPL has been identified by government agencies as a vehicle for civic engagement and oversight in the former Sidewalk Toronto smart city plan.
