Begin your net-zero journey by exploring the Net Zero Introductory Guide. This guide supports home and building owners, managers, and operators in understanding what net‑zero buildings means in practice — and why they are central to Toronto’s climate goals. It offers clear, practical direction on achievable pathways to net‑zero, showing how deep energy retrofits, electrification, and renewable energy can dramatically cut emissions across Toronto’s building stock. Beyond outlining what it takes to pursue deep energy retrofits, the guide highlights the broader value they unlock for both owners and communities: reduced operating costs, better comfort and indoor health, improved resilience during extreme weather, and strengthened long‑term asset performance.
Use this guide to familiarize yourself with key net‑zero concepts, explore how to use subsequent guides and and plan your next steps to unlock economic, social, and environmental benefits on the pathway to a net‑zero Toronto by 2040.
Take the next step toward net-zero by exploring building-specific sector guides. These guides span nearly every building type in Toronto—from single family homes to institutional facilities and large commercial buildings—and highlight net zero retrofit measures tailored to each sector. These resources provide practical, actionable strategies to help building owners and operators plan and implement deep energy retrofits: comprehensive upgrades that modernize building systems, strengthen the envelope, and optimize overall energy performance. Each guide also outlines estimated costs and potential savings, supporting informed decision making and helping you choose the right pathway for your building.
Use these guides to identify the systems and retrofit measures most relevant to your home or building, and to map out your step by step pathway to net zero.
