Mitigating the Urban Heat Island Effect in Canadian Metropolitan Areas

A Comparative Study of Nature-Based Solutions and Reflective Infrastructure

Abstract

As global temperatures rise, Canadian urban centers are experiencing intensified Urban Heat Island (UHI) effects, leading to increased energy consumption and significant public health risks. This article presents a comparative analysis of mitigation strategies across three major metropolitan areas: Toronto, Vancouver, and Montreal. The research evaluates the efficacy of nature-based solutions—including green roofs and expanded urban canopies—against high-albedo reflective infrastructure. Utilizing satellite thermal mapping and local sensor data, the study identifies critical "heat hotspots" and proposes a localized resilience framework for urban planners. This foundational article for CJCRS establishes the necessity of integrating thermodynamic modeling into sustainable municipal policy.
