This is a difficult level to achieve, and every sector, including housing, was given targets and some incentives. Support for housing came in the form of rebates on energy-saving retrofits, which were available through the EnerGuide for Houses program, and consumer information programs. One such program, the One-Tonne (metric ton) Challenge, asked Canadian homeowners to reduce their annual GHG emissions from an average of 5 metric tons to an average of 4 metric tons—a 20% reduction—and suggested ways to achieve this reduction.

In 2004 she received funding from the Canada Mortgage and Housing Corporation (CMHC) to undertake a neighborhood-based GHG reduction experiment.
