The report asserts that while the 1990 Clean Air Act Amendments and Canadian programs reduced sulfur dioxide and nitrogen oxide emissions, acid rain remains a major problem due to the cumulative acid burden from 150 years of industrial activity. It highlights ongoing threats to salmon in Nova Scotia, lakes in Canada, and aquatic life in New York, Virginia, and Pennsylvania. The document concludes that emissions cuts of up to 80 percent beyond the 1990 amendments are necessary for biological recovery to begin by mid-century, which can be achieved through energy efficiency, renewables, cleaner fuels, and pollution control.

The report asserts that while the 1990 Clean Air Act Amendments reduced sulfur dioxide and nitrogen oxide emissions, ecosystems in North America remain damaged due to a 150-year accumulation of acidic compounds. It documents ongoing damage to aquatic life, forests, and wildlife, and argues that biological recovery requires emission cuts up to 80 percent beyond the 1990 mandates. The authors state that affordable technologies, such as scrubbers and renewable energy, are available to achieve these deeper reductions.

The report analyzes the regulatory landscape of aesthetic pesticides in Canada, noting that while over 200 municipal bylaws have been adopted since the 2001 Supreme Court decision in Hudson v. Spraytech, effectiveness varies by scope and enforcement. It highlights that 'white lists' of safe products and broad bans covering all landscaping elements are more effective than narrow bans limited to lawns. Evidence from Ontario and Toronto shows significant reductions in pesticide presence in water and usage (up to 83% and 57% respectively) following bans. The document recommends removing exceptions for golf courses, implementing permit systems, and combining legal mechanisms with public awareness and enforcement.

The document details the environmental and health impacts of Alberta's coal-fired power plants, noting that in 2014, 68% of the province's electricity was generated from coal. It highlights that these plants are significant sources of sulphur dioxide, nitrogen oxides, fine particulate matter, mercury, and greenhouse gases, with 2011 emissions totaling 43 megatonnes of GHG. The authors propose a transition plan to reach 0% coal reliance by 2030, increasing renewable energy to 40% and reducing electricity demand through energy efficiency by 20%. The strategy discourages increased reliance on stand-alone natural gas due to production-related GHG emissions and suggests mechanisms for phase-out such as legislated closures, lifespan caps, or carbon pricing.

The paper argues that Canada faces an 'implementation deficit' in climate adaptation, where high-level commitments have not translated into concrete action due to poor interdepartmental coordination and a lack of systematic mainstreaming. It proposes several policy options to embed adaptation into government decision-making, including the use of statute law, central policy directives, the creation of a dedicated adaptation policy unit, and the enhancement of ex ante appraisal tools.

The document argues that Canada has historically struggled to translate high-level climate adaptation aspirations into concrete action due to a lack of interministerial coordination and systematic integration. It proposes moving beyond voluntary, informal approaches toward a 'whole-of-government' approach. Key recommendations include enacting a national climate change adaptation law, issuing centralized policy directives, establishing a dedicated central adaptation policy unit, and utilizing ex ante evaluation tools. The paper highlights the UK's Climate Change Act as a successful model of legislative accountability and notes that most OECD countries possess specialized units for adaptation coordination, a feature currently lacking in Canada.

Atlantic Canada faces significant fiscal and economic risks due to its reliance on oil, gas, and coal, particularly in Newfoundland and Labrador and New Brunswick. While the region shows momentum in clean technology—led by Nova Scotia—and possesses strong natural resource advantages in wind, hydro, and tidal energy, scaling these opportunities is hindered by a lack of capital, a shortage of skilled STEM labour, and a mismatch between the location of new growth and transition-vulnerable rural communities.

The report identifies Atlantic Canada as a leader in decoupling GDP growth from greenhouse gas emissions, though it faces significant fiscal risks due to a reliance on oil, gas, and coal. While Nova Scotia is a hub for transition-related innovation in batteries, smart grids, and low-carbon shipping, regional companies generally remain small and undercapitalized. Vulnerabilities are concentrated in rural areas and specific provinces, notably Newfoundland and Labrador, where oil and gas sectors are critical to government revenue.

The document argues that while Canada has made progress in decarbonizing power supply, achieving net-zero requires Energy Systems Integration (ESI)—the coordination of energy systems across multiple pathways and scales. It examines five key ESI technologies (electric vehicles, heat pumps, demand response, distributed generation, and hydrogen) and finds that Canadian policy is currently too siloed, relying on voluntary 'soft' incentives rather than systemic market reforms or mandatory legislation. The author highlights significant gaps in information, governance, and implementation, suggesting that a holistic, pan-system approach to modelling and planning is essential to avoid sub-optimal infrastructure lock-in.

The paper analyzes the diverse structures of Canadian provincial electricity markets, noting that a lack of coordination creates economic inefficiencies and hinders the integration of renewable energy. It identifies six primary challenges to integration, including constitutional jurisdictions and vested interests in price differentials. To address these, the author proposes four strategies: enhancing bilateral projects, adopting a bottom-up Nordic-style collaborative model, utilizing the Canadian Free Trade Agreement, or implementing a federal healthcare-type framework of shared principles.

The document identifies a stark divide in Canada's electricity sector between low-emitting provinces (B.C., Manitoba, Quebec, Newfoundland and Labrador, and Ontario) and fossil fuel-based provinces (Alberta, Saskatchewan, New Brunswick, and Nova Scotia). To achieve net zero, the author proposes five integrated pathways: expanding variable renewable energy, implementing clean firm supply, enhancing interprovincial transmission, increasing demand flexibility, and deploying energy storage. While wind and solar are now the lowest-cost energy sources, their integration requires complementary resources to manage intermittency and seasonal variation, particularly in Canada's high-latitude environment.

The report finds that while electrification will increase electricity use, total energy spending for Canadian households is expected to decline. However, the costs of expanding electricity infrastructure may fall regressively, disproportionately impacting lower-income households. The authors analyze rate-design changes and government funding mechanisms as tools to improve equity, concluding that means-tested fixed charges and progressive tax-based funding can insulate vulnerable populations from rising costs.

The document analyzes the diverse structures of Canada's provincial electricity markets, noting that a lack of coordination creates economic inefficiencies and hinders the integration of renewable energy. It identifies key barriers to integration, such as constitutional jurisdictional splits and political inertia, and proposes four strategies—bilateral collaboration, a Nordic-inspired bottom-up approach, a free-trade framework, and a health-care-style principles-based model—to foster a more integrated national grid necessary for deep decarbonization.

The report examines the current state of Energy Systems Integration (ESI) in Canada, focusing on five key technologies: electric vehicles, heat pumps, demand response, distributed generation, and hydrogen. It argues that while Canada has successfully decarbonized its electricity grid, further progress requires coordinating energy vectors and scales. The author identifies significant barriers, including fragmented governance, a lack of integrated modeling, and a policy landscape dominated by voluntary 'soft' incentives rather than systemic mandates. The document recommends replacing sectoral subsidies with market reforms that remunerate grid flexibility and implementing integrated modeling platforms to guide coordinated infrastructure investments.

The document outlines a strategy for Canada to achieve a net-zero electricity sector by 2050, noting a sharp divide between 'clean' provinces (e.g., Quebec, Ontario) and those reliant on fossil fuels (e.g., Alberta, Saskatchewan). It proposes five key technical trajectories: increasing variable renewable energy, securing clean firm capacity, enhancing interprovincial transmission, improving demand flexibility, and deploying long-duration storage. The author argues that while the economic cost of wind and solar has plummeted, the primary barriers are now financial uncertainty regarding carbon pricing and the technical need for firm capacity and seasonal storage to manage intermittency.

The report quantifies the economic burden of climate change on Canada, predicting significant GDP losses, job reductions, and decreased household income by the end of the century. It highlights a 'broken window fallacy' where spending on repairs masks the opportunity cost of lost productive investment. The analysis finds that the North and Alberta are most vulnerable, and that combining proactive adaptation with global emission reductions could eliminate 75% of real GDP losses, with adaptation investments yielding a return of $13 to $15 for every dollar spent.
