How to Stack Canadian Green Rebates and Maximize Your Savings

Most Canadian homeowners leave money on the table by claiming only one rebate when they could be stacking two or three. The best stacks combine a provincial or utility program as the foundation, with federal programs added on top. Here's how to do it.

Key principle: Federal programs are designed to stack with provincial ones. The government built the system this way intentionally. Stacking is not gaming the system — it's exactly what the programs intend.

The Stacking Rule

Programs that cover different costs or different upgrades generally stack freely. Programs that cover the same upgrade usually cannot be combined. The trick is knowing which category each program falls into.

The 4 Rules of Successful Stacking

Always start with the provincial program. Federal programs are often designed as top-ups to provincial ones. Know your provincial program first, then find what federal programs stack on top.
Do the paperwork in order. Many programs require pre-registration or pre-assessment before work starts. For bundled paths, get your assessment before touching anything. Skipping this step loses the rebate.
Don't claim the same upgrade twice. If your provincial program covers a heat pump, you generally can't stack a different provincial program for the same heat pump. Federal and provincial programs covering different costs can stack.
Check the stacksWith rules for each program. Most programs explicitly list which other programs they are compatible with. Our rebate finder shows this for every program result.

What Cannot Be Stacked

Two provincial heat pump programs covering the same installation
EVAP and iZEV (iZEV is closed — this is no longer relevant)

The Audit Advantage

A pre-retrofit EnerGuide energy audit unlocks the bundled upgrade path in most provinces. Spending $300–$600 on an audit can unlock thousands more in rebates by making you eligible for the multi-measure stacking paths in HRS (Ontario), Rénoclimat (Quebec), and SaveEnergyNB (New Brunswick).
