  To assess the impact of climate change on the Canadian economy, we
investigate and model the relationship between seasonal climate variables and
economic growth across provinces and economic sectors. We further provide
projections of climate change impacts up to the year 2050, taking into account
the diverse climate change patterns and economic conditions across Canada. Our
results indicate that rising Fall temperature anomalies have a notable adverse
impact on Canadian economic growth. Province-wide, Saskatchewan and Manitoba
are anticipated to experience the most substantial declines, whereas British
Columbia and the Maritime provinces will be less impacted. Industry-wide,
Mining is projected to see the greatest benefits, while Agriculture and
Manufacturing are projected to have the most significant downturns. The
disparities of climate change effects between provinces and industries
highlight the need for governments to tailor their policies accordingly, and
offer targeted assistance to regions and industries that are particularly
vulnerable in the face of climate change. Targeted approaches to climate change
mitigation are likely to be more effective than one-size-fits-all policies for
the whole economy.
