NRCan-licensed service organization
Not one of the seven organizations approved for Ontario's Home Renovation Savings assessment path. Its EnerGuide evaluations are official and still count for planning, financing and other programs, but only assessments from the seven HRSP-approved organizations qualify for the $600 rebate and the assessment-path upgrade rebates.
A non-profit ecology centre in Aurora and one of the longest-standing licensed service organizations in the GTA. It publishes its evaluation prices, the kind of transparency this directory exists to reward.
