The document is intended to lay the groundwork for a forthcoming comprehensive policy and to facilitate consultation with business, municipalities, industry, Indigenous groups and the public. The paper suggests implementing new regulations and market instruments, including carbon pricing, which will realign economic incentives and disincentives with climate change mitigation goals. The paper emphasizes the importance of climate-smart infrastructure and transportation development to help merge economic growth, resilience, energy efficiency, and emissions reduction strategies. It concludes with a call for the opinions of stakeholders, including how to build upon existing successful policies, which industries to target, how to design climate-friendly built communities, and which carbon pricing mechanism might suit Ontario best.
