What is Toronto Green Standard v4, and what tier applies to my renovation?
Answered by AskBaily Editorial · Updated
Short answer
Toronto Green Standard v4 (effective 2022, updated 2024) is Toronto's sustainability overlay — four tiers of performance requirements on energy, water, waste, ecology, and air quality. Tier 1 is mandatory on substantial residential renovations and additions; Tiers 2-4 are voluntary but incentivized through Development Charge rebates. Tier 1 drives envelope performance, ERV/HRV, and heat-pump readiness on most substantial scopes.
