7 Top Environmental Issues in Toronto & Their Solutions

Toronto, the largest city in Canada, faces a range of environmental issues that demand attention and action.

This article aims to delve into these environmental issues in Toronto, analyze their causes and impacts, and explore their solutions. Read on! 

It can be challenging to navigate the numerous climate policies, strategies, plans, and programs at every level of government.

Toronto faces various environmental issues that require attention. These issues encompass areas such as pollution, waste management, urban development, climate change, and biodiversity. 

Efforts are being made to address these issues through sustainable practices, environmental policies, and community engagement.

The Toronto Environmental Alliance (TEA), has actively worked at a local level to address the environmental challenges faced by Toronto’s urban areas. 

They have been advocates for a sustainable, healthy, and fair city, representing the interests of all residents in Toronto. 

TEA addresses issues of Climate Change, Waste Reduction, and Toxics in the environment. And, out of a wide variety of others, we have highlighted the top 7 major environmental problems in Toronto, addressing their causes, effects, and preventive measures.

Top Environmental Issues in Toronto, Challenges and Sustainable Solutions

  • Waste management issues
  • Climate change
  • Water Pollution
  • Industrial Pollution & Urban Sprawl
  • Greenhouse Gas Emissions
  • Biodiversity Loss
  • Noise Pollution

Waste Management Issues

Waste management is a pressing environmental issue in Toronto. The city generates a significant amount of waste that requires proper disposal and recycling. 

Estimated Research shows that the City of Toronto handles nearly 900,000 tonnes of waste annually. This involves the allocation of funds, energy, and resources, and it also occupies valuable space in landfills. 

Strategies such as waste reduction initiatives, recycling programs, and landfill diversion efforts are being implemented to address waste management issues and promote a circular economy integral to Toronto’s waste management strategy.

Climate Change

Climate change poses significant challenges for Toronto. The city is witnessing a rise in the occurrence of more frequent and severe weather issues. These include increased frequency of extreme weather events, rising temperatures, and changing precipitation patterns.

According to a report by the Canadian Institute for Climate Choices, the costs of climate change and weather-related disasters are costing Canadian households billions of dollars. 

Toronto experienced two significant weather events in 2013, providing a glimpse into the potential impacts of climate change. The adverse effects of climate change and the subsequent severe weather events pose risks to both human health and the surrounding environment.

Climate change arises from the unnecessary combustion of gasoline, oil, coal, and natural gas for heating homes, fueling vehicles, producing goods, and generating electricity. Total reliance on fossil fuels has detrimental effects on the climate and air quality. 

Energy conservation and the use of renewable energy sources like wind and solar power are equally feasible from a technical and economic standpoint. 

These alternatives can aid reduce pollution, creating employment, and income opportunities nationwide, and reducing energy costs as well.

Water Pollution

Water pollution in Toronto stems from various sources, including stormwater runoff, sewage overflow, and industrial discharges. 

These contaminants degrade water quality, harm aquatic ecosystems, and pose risks to human health. 

These water systems are contaminated with more than just bacteria from human waste. Pharmaceuticals, harsh cleaning products, household hazards, and also businesses and institutions dispose of chemicals through the sewer system 

The city has invested in wastewater treatment upgrades, implementing stormwater management strategies, and raising awareness about water conservation to mitigate water pollution.

TEA plays an important role in monitoring existing policies, such as the Sewers By-law, to ensure that water polluters are being held accountable.

Industrial Pollution & Urban Sprawl

Industrial pollution can have detrimental effects on the environment and public health. Toronto addresses industrial pollution through regulations, emission controls, and monitoring programs. 

Urban sprawl refers to the rapid and unplanned expansion of urban areas, often at the expense of natural habitats and agricultural land. 

Toronto has experienced significant urban sprawl, leading to increased traffic congestion, loss of green spaces, and strain on infrastructure. 

The city promotes sustainable industrial practices and encourages industries to adopt cleaner technologies and pollution prevention measures.

Urban planning initiatives and smart growth strategies aim to manage and mitigate the impacts of urban sprawl.

Greenhouse Gas Emissions

According to the City of Toronto’s latest greenhouse gas emissions inventory which monitors and detects both direct and indirect greenhouse gas (GHG) emissions.

Three dominant sectors were identified as the main sources of greenhouse gas emissions in Toronto namely : 

  • Buildings: Residential and commercial structures mainly rely on the combustion of natural gas to provide heat.
  • Transportation: This includes stems Emitted from individual vehicles.
  • Waste Materials The main source of emissions from waste is primarily related to landfill sites.

Greenhouse gas emissions contribute to climate change, and Toronto is taking measures to reduce its carbon footprint. 

These efforts include promoting energy efficiency, transitioning to renewable energy sources, encouraging sustainable transportation, and implementing green building practices to lower greenhouse gas emissions. 

Biodiversity Loss

Biodiversity loss is a concern in Toronto due to urbanization and habitat fragmentation. The city recognizes the importance of preserving and restoring biodiversity for ecological balance. 

The Toronto City Council approved the city’s inaugural Biodiversity Strategy on October 3, 2019. The objective of this strategy is to promote a healthier and more resilient biodiversity while raising awareness about nature in Toronto. 

Efforts are being made to protect natural areas, enhance urban green spaces, promote native species conservation, and support citizen-led initiatives that contribute to biodiversity conservation.

Noise Pollution

Noise pollution is an environmental problem that affects the quality of life in Toronto. Sources of noise pollution include traffic, construction activities, and commercial establishments. 

The city implements regulations and noise control measures to minimize the impact of noise pollution on residents. The Noise Bylaw establishes guidelines for noise control in Toronto, which include specific limits on decibel levels and time constraints for certain noise sources.
