Academic literature on the topic 'Automobile parking – Ontario – Toronto'

Between 1945 and 1965, the Hamilton Farmers' Market was hailed as both an irreplaceable cultural and historical gem, and condemned as an antiquated institution not worth the land it occupied. The market debates occurred in the midst of post-World War II suburban sprawl, fuelled and facilitated by the automobile. This change in the postwar landscape accommodated the rise of powerful modernist ideology as well as a traditionalist response. Debates over the market's fate touched on reducing, relocating, or eliminating the market completely. The chosen solution—constructing a parking ramp on the market site, and housing the market on the ground level of the structure—was implemented by October 1960. This was a victory for the city's modernizers, and foreshadowed the more extensive urban renewal efforts that dominated regional politics in the late 1960s and 1970s.

The paper summarizes the changes in modal transport choice behaviour that occurred in the Toronto region between 1986 and 1991. The evidence presented shows that the region has become more dependent on automobile travel, making the sustainable transport targets adopted by Canada even more difficult to achieve. These changes are analyzed in terms of (i) changes in the size of the socio-demographic market segments that influence modal transport choice, (ii) changes in the choice probabilities of these market segments, and (iii) changes in the spatial structure of the Toronto region. The socio-demographic changes during the 1986–1991 period are less favourable to public transport and the probabilities of selecting public transport for the journey to work have decreased substantially for most of the market segments. The paper shows the overwhelming influence of development density on modal transport choice and the beneficial influence of adjacent high density employment and residential densities on the use of nonmotorized travel. The paper argues that the excessive auto-dependency of the Toronto region is likely to change only if high density suburban development forms are created and comprehensive road and parking pricing schemes introduced. Key words: urban transport, transport mode choice, public transport, regional development.

INTRODUCTION Winter snow and ice can have a significant impact on our mobility, whether on foot or by car. Alongside plowing, arguably the greatest tool in combating snow and ice is salt. The most commonly used salt for winter maintenance is Sodium Chloride (NaCl), the same salt used in food and water softeners, is applied to roads, sidewalks, and parking lots as it is an effective deicer when temperatures are between 0°C and −12°C. Studies have shown that deicing with salt reduces accidents by 88% and injuries by 85% (Salt Institute 2017). The effectiveness of road salt, as well as its relative affordability, means that as much as four million tonnes may be applied annually in Canada for deicing (Environment Canada 2012). However, while salt is relatively inexpensive to purchase, there are a number of external costs that are becoming increasingly apparent. These include corrosion of vehicles and infrastructure like concrete, bridges, and water mains; damage and staining to the interior and exterior of buildings; impacts to roadside vegetation and soils; and the contamination of fresh water. In fact, the environmental impacts are such that it prompted Environment Canada to propose that winter salt be considered a toxic substance primarily due to the quantity that is applied annually (Environment Canada 2001). The Lake Simcoe watershed, approximately 3,400km2 in size, is situated just 20km north of Toronto, Ontario, with the southern portion of the watershed being considered part of the Greater Toronto Area (GTA), the most populous metropolitan area in Canada. As part of the GTA, the Lake Simcoe watershed has experienced and continues to experience considerable growth, and with this growth comes an increase in the amount of impervious surfaces requiring winter salting. Indeed, chloride has been showing a strong increasing trend in the urban creeks and in Lake Simcoe itself over the last 30 years. Even rural creeks are showing an increasing trend, albeit not as severe, nor are the concentrations of chloride reaching the same levels (LSRCA 2015). The highest chloride level recorded in a Lake Simcoe tributary was 6,120mg/l in the winter of 2013. Chloride guidelines for the protection of aquatic ecosystems utilize a guideline of 120mg/L for chronic exposure and 640mg/L for acute exposure (CCME 2011). While the high value recorded in the Lake Simcoe tributary greatly exceeds these guidelines, it is still drastically lower than values being recorded in larger, intensively urbanized catchments such as Cooksville Creek in Mississauga, Ontario, which sees concentrations in excess of 20,000 mg/L, the concentration of sea water, nearly every winter (Credit Valley Conservation personal comm). Similarly, in July of 2011 a small population of Atlantic blue crabs, a marine species, was found surviving in Mimico Creek in Toronto (Toronto Star: May 26, 2012). That a marine species was able to survive in this fresh water creek in summer demonstrates that the impacts of winter salt are not just limited to winter but are impacting shallow groundwater and thus summer baseflow, maintaining high chloride concentrations year round. The same is being seen in some urban creeks in the Lake Simcoe watershed, with summer baseflow concentrations exceeding the chronic guideline and trending upwards (LSRCA unpublished). While not yet as extreme as rivers in the more densely urbanized parts of the GTA, these examples foreshadow what is in store for Lake Simcoe rivers if current winter salt practices continue along with the projected urban growth. During the winter of 2012 an estimated 99,300 tonnes of salt was applied in the Lake Simcoe watershed, an amount that equals nearly 250kg of salt per capita, or ~3 times the average person's body weight in salt. This estimate was generated through a survey of local road agencies along with the total area of commercial/institutional parking lots within the watershed. The exercise served to highlight a knowledge gap around application practices and rates in commercial/institutional parking lots. The majority of road agencies were found to record annual volumes, application dates and rates whereas literature values range from 10–40% of the salt applied in a catchment come from commercial/institutional parking lots (Perera et al, 2009; Trowbridge et al, 2010; Lake Simcoe Region Conservation Authority, 2015), and a survey of winter maintenance contractors cite an average value of approximately 58g/m2/application (Fu et al, 2013) ( Figure 1 ). [Figure: see text] While these values were used in the estimation as they were the best available, observational data suggested these may be on the conservative side ( Figure 2 ). [Figure: see text] Therefore, monitoring of a 14 ha commercial lot was undertaken for the winters of 2014/15, 2015/16, and 2016/17 to better quantify the amount of salt coming from this type of land use. The winters of 2014/15 and 2016/17 saw similar applications of 1,067 and 1,010 tonnes applied respectively, while the mild winter of 2015/16 saw 556 tonnes applied. While the amounts varied somewhat each winter, the impacts downstream were consistent. Maximum concentrations recorded in the melt water reached 3.5 to 4 times the salt concentration of sea water every winter, equating to chloride concentrations of 70,000mg/L to 85,000mg/L; two orders of magnitude above the water quality guideline. As with most parking lots constructed in the last two decades, the runoff from this parking lot is captured in a stormwater pond prior to entering the receiving watercourse. Interestingly, the winter salt also caused persistent chemical stratification in the permanent pool of the pond. The pond was monitored with continuous monitors for the ice free period of 2015 and 2016 (April to December) during which the bottom water chloride concentration remained distinct from the surface chloride concentration, indicating stratification ( Figure 3 ). This has two significant implications; first of which is that this pond, and therefore many other ponds like it, may not be functioning as designed which is leading to diminished performance (McEnroe 2012, Marsalek 2003). Second is that ponds are acting as salt reservoirs, slowly releasing salt year round and contributing to river chloride concentrations that continually exceed the chronic exposure guideline and thereby exposing aquatic life to harmful concentrations during sensitive life cycle stages. [Figure: see text] To determine the extent to which the catchment land use type impacts stormwater ponds, chemical profiles were measured on three ponds in February 2017. The catchments included the 24.6 ha commercial catchment with 14 ha of salt application surface, an institutional catchment (14.3 ha) with 6 ha of salt application area that includes parking lots and roads, and a 16.4 ha residential catchment with 3 ha of salt application area comprised of tertiary municipal roads. Interestingly, all three ponds showed chemical stratification, with the severity of the stratification and highest chloride concentrations relating to the amount of salt application area in the catchment. The residential pond yielded a maximum chloride concentration of 3,115mg/L in the bottom waters, the institutional yielded 16,144mg/L, and the commercial yielded 25,530 mg/L with chloride concentrations in the bottom 0.5m of the pond exceeding that of sea water. The maximum chloride concentration recorded in the receiving watercourse downstream of the commercial lot was measured at 5,406 mg/L, well in excess of the acute guideline of 640 mg/L. These results highlight that commercial parking lots are not only receiving a significant volume of salt but are also having the most dramatic impacts on receiving stormwater infrastructure and watercourses.

Regional commuter rail has become an important means of traveling to urban employment centers across North America, but planners are faced with the challenge of connecting commuters from their origin or destination locations to a train station. Cycling may be an efficient and low-cost way of taking these transit-access trips. However, cycling behavior of rail commuters, particularly in a suburban context, remains understudied. This research examined perceptions of cycling and current cycling behavior of 257 transit users from three suburban commuter rail stations in the Toronto region, Canada. Using a cluster analysis approach, four distinct cyclist types were identified, namely: recreational cyclists (29%), all-purpose cyclists (10%), safety-conscious occasional cyclists (33%), and facility-demanding occasional cyclists (28%). Differences between these groups included different mode-choice motivations, tolerance for adverse weather conditions, comfort bicycling in various hypothetical traffic/infrastructure conditions, and current frequency of cycling for transportation and recreational purposes. The safety-conscious group included a higher percentage of women compared to other groups. Overall, 32.5% of regional transit users would be interested in cycling more often to rail stations. A higher proportion of recreational cyclists (compared to other groups) were “interested first-mile cyclists”, whereas the safety-conscious group had a significantly greater proportion of “uninterested” respondents. With careful planning of bicycle infrastructure and awareness campaigns targeting perceptions of cycling, there is much potential for cycling to accommodate a greater proportion of transit-access trips in suburban communities, reducing demand for automobile parking at transit stations.

Abstract Introduction/Background The Canadian Paediatric Society (CPS) recently released the “Global climate change and health of Canadian Children” statement. As climate rapidly evolves from “change” to “crisis” there is an increasing pressure toward sustainable conferencing. Knowing the value of attending meetings, the growing body of literature evaluating travel-related carbon cost and convention sustainability can inform environmental harm minimization. Conferences can pressure venues to increase sustainability by choosing sites and venues wisely and communicating their requirements to rejected venues. They can also offer carbon offset purchase through credible companies (e.g. Gold Standard). Over the last 10 years the CPS has conducted its Annual General Meeting (AGM) at host cities that reflect Canada’s large geographic footprint. Venues included both hotel and standalone conference centers. There is no published evaluation of sustainable practices for CPS meetings. Objectives Evaluate the past 10 CPS Annual General Meetings (AGMs) for: Design/Methods Travel-related carbon cost was estimated with a round-trip calculator for economy seating the most direct available flights (https://co2.myclimate.org/en/offset_further_emissions). Cities of origin for attendee were the 11 CaRMS-matched pediatric residency training programs (https://www.carms.ca/match/psm/program-descriptions/). Venues were evaluated based on current publicly available self-reported information using conference sustainability criteria suggested through a literature review and public rating tools (Green Key, Quality Standards of the International Association of Convention Centres). Ground transportation from the airport was scored /3 by: public transport from airport (1), formal shared transport (1), fee deterrence for parking (1). Venue type was split by hotel-associated (H) and standalone convention centre (CC) meeting facilities. Sustainability of meeting facilities was divided into supports /2 (rentable supports, links to local vendors, catering and personnel) for exhibitors (1) and event planners (1), policies /3 by: sustainability, promotion of a green community (1), and waste management (1), and walkability from accommodation /1. Results The last 10 CPS AGMs were held in western (3; Vancouver 2010, Edmonton 2013, Vancouver 2017), eastern (1; Charlottetown 2016) and central (6; Quebec City 2011, London 2012, Montreal 2014, Toronto 2015, Quebec City 2018, Toronto 2019) provinces; in 2020 it is in Vancouver. Central Canada sites had the lowest air travel carbon cost per attendee. Average air travel-related carbon cost per attendee for different host cities ranged from 0.479 (London) to 0.919 (Vancouver) tonnes, with Ontario and Quebec sites averaging 0.518, Charlottetown 0.654 and Edmonton 0.756 tonnes. Ground transportation scores differed by city from Montreal (3/3 with public transit, formal transportation share and parking fees to dissuade driving) to London (0/3), with more favorable public transit options in larger cities. Venues differed when divided by hotel with meeting facilities (H) vs standalone conference center (CC), with CC outranking H for clearly posted sustainability plans (1.6 vs 1.2/2; 2=venue-specific, 1=company chain policy, 0=no plan), green and sustainable community building plans (1.6 vs 1.2/2; 2=greening local communities, 1=company chain policy, 0=no plan) and green waste management policies (1.2 vs 0/2; 2=venue-specific, 1=company chain policy, 0=no plan). Walkable accommodation was equal and present for all venues, with attached accommodation for all but one CC (Montreal), which had immediately adjacent hotels available. Conclusion As expected, the carbon cost of air transportation per attendee was lower in central provinces. Ground transportation from the airport was better in larger host cities. Standalone conference centres had more sustainable event support and locally focused policies regarding sustainability, environmentally friendly community building initiatives and waste management solutions, three major components of “greening” conferences. Based on the available resources across Canada, we recommend that the CPS considers these sustainability criteria in planning future events.
