Climate change is making heatwaves in Canada more frequent, intense, and prolonged, with the country warming twice as fast as the global average. These events are linked to increased mortality, severe health risks, and the amplification of wildfires, such as the 2021 British Columbia heat dome. The economic burden is significant, with projected annual costs of $3 billion for health-related deaths and quality of life losses by mid-century, alongside billions in infrastructure damage and productivity losses. Adaptation strategies, including indoor cooling and resilient infrastructure, are recommended to mitigate these risks.

Climate change is making heat waves in Canada hotter, longer, and more frequent, with the country warming twice as fast as the global average. These events are linked to increased mortality, severe health issues, and the intensification of wildfires. Economic burdens include billions in healthcare costs, societal losses from premature deaths, and infrastructure damage. Adaptation strategies such as indoor cooling, green infrastructure, and improved urban design are recommended to mitigate these risks.

The document argues that fossil fuel sponsorship of political gatherings, specifically the UBCM Convention, constitutes greenwashing and improperly influences municipal decision-making. It links fossil fuel combustion to severe health crises, including 8.1 million annual global deaths from air pollution and extreme weather events in British Columbia such as the 2021 heat dome and historic wildfires. The authors call for a total ban on fossil fuel advertising and sponsorship in BC municipalities, drawing parallels to the historical ban on tobacco industry influence in medicine.

The paper examines the 2021 climate disasters in the Fraser Canyon region, specifically the destruction of Lytton, to highlight the fragility of Canadian infrastructure. It presents the Kanaka Bar Indian Band's strategies for water, food, and shelter security as scalable examples of climate adaptation and resilience.

The document examines the devastation of Lytton in 2021 and proposes a reconstruction framework based on 'physiological foundations' to ensure climate resilience. It highlights the Kanaka Bar Indian Band's proactive investments in site-specific weather monitoring, gravity-fed water systems, controlled-environment agriculture, and passive housing design as scalable models for 62,000 other high-risk Canadian communities.

The document examines the impact of the 2021 heat wave on five First Nations in British Columbia, highlighting how colonial housing policies increased vulnerability while community solidarity and traditional knowledge provided critical protection. It details specific regional impacts—from urban challenges in the Tsleil-Waututh Nation to the infrastructure dependencies of the Haíɫzaqv (Heiltsuk Nation)—and argues for resilience planning rooted in Indigenous rights and localized data.

The June 2021 heat wave in British Columbia was the deadliest disaster in the province's history, resulting in 619 direct heat-related deaths. The report estimates the societal cost of these lives lost at $5.5 billion using the Value of a Statistical Life (VSL) metric. Beyond mortality, the event caused $12 million in healthcare costs, significant agricultural revenue losses (at least $25 million), and disruptions to electricity and transportation infrastructure. Vulnerabilities were exacerbated by a lack of mechanical cooling in homes, inadequate urban greening, and institutional failures in disaster response and communication. The report argues that without adaptation, heat-related hospitalizations could double by 2030 and annual deaths could average 1,370 by 2030. Key recommendations include updating building codes for mechanical cooling, increasing urban forest canopies, improving weather warning lead times to three days, and implementing independent public reviews of disaster responses.

The Canadian Association of Physicians for the Environment has issued a formal letter to the Union of BC Municipalities (UBCM) protesting the acceptance of sponsorships from fossil fuel entities. The physicians argue that such partnerships create a conflict of interest and undermine municipal climate action, particularly given the severe health and economic impacts of climate-induced disasters in British Columbia and globally.

A rapid analysis of the June 2021 Pacific Northwest heatwave concludes that the event was virtually impossible without human-caused climate change. The study estimates the event as a 1-in-1000-year occurrence in the current climate, noting it was approximately 2°C hotter than it would have been before the industrial revolution. Projections indicate that with 2°C of global warming, such events could occur every 5 to 10 years.

The report concludes that the June 2021 Pacific Northwest heatwave was virtually impossible without human-caused climate change, estimating it as a 1-in-1000 year event in the current climate. The analysis indicates the event was approximately 2°C hotter than it would have been in a pre-industrial climate and would have been at least 150 times rarer without anthropogenic warming. Future projections suggest that in a world with 2°C of global warming, such an event would occur every 5 to 10 years and be another degree hotter. Meteorological drivers included an 'omega-block' high-pressure system and dry antecedent soil conditions, while natural variability modes like ENSO and PDO played little to no role.

The Canadian Association of Physicians for the Environment calls for British Columbia to update its Building Code and Energy Step Code to prohibit new gas connections by 2022 and set deadlines for existing buildings to switch to clean energy. The briefing highlights that buildings cause 12% of the province's greenhouse gas emissions and that natural gas use contributes to health risks, including childhood asthma from indoor nitrogen dioxide and lung disease linked to hydraulic fracturing in the Peace region. It notes that retrofitting a home from gas to electric currently costs over $20,000, making the 'future-proofing' of new buildings a cost-effective necessity to meet the province's goal of net-zero emissions by 2050.
