Dear Customer:

The Canada Greener Homes Grant will invest $2.6 billion over 7 years to help up to 700,000 Canadian homeowners across the country improve the energy efficiency of their homes and reduce their energy bills.

Homeowners will be able to receive grants of up to $5,000 to make energy-efficient retrofits to their homes, and up to $600 to help with the cost of an EnerGuide home energy evaluation.

This is an amazing marketing opportunity for our industry, but when we dig deeper it won’t be much more than that.

Applicants now need to make sure a pre – and post-retrofit EnerGuide evaluation gets completed – by an NRCan registered energy advisor (there will be 2,000 of these hired) before and after they complete their retrofit upgrades. EnerGuide evaluations that were completed before December 1, 2020, will not be eligible for reimbursement.

According to the program, retrofits recommended by your energy adviser are the only ones eligible for reimbursement and a list should be included in your pre-evaluation.

A new window unit can be inserted into the existing frame of an old window, but replacements of only the glass, sash or door without a frame are not eligible.

The grant will reimburse up to a maximum of $5,000 plus the $600 for the entire retrofit project which will include windows, doors, and HVAC. A maximum of $250 (for super high-efficiency performance windows – $125 for lower efficiency windows) per rough opening and $125 to replace hinged doors, with or without sidelights or transoms from ENERGY STAR certified models.

A rough opening is defined as the structural framing in a wall or roof, separating a heated from unheated space, that creates an opening for the installation of a window, door or skylight. For example, a bay window with three window units installed into one rough opening is eligible for only one grant. This is important to note.

The program encounters major shortfalls when it addresses the efficiency requirements of the replacement door or window.


The replacement product must have an energy rating of equal to or greater to 34 to be eligible for the $125 grant. A door with a fan lite has a rating of 20 which does not qualify. Consumers will not sacrifice appearance, taste and preference to get $125.


For a window to meet the $125 grant it must have the following energy rating:

U-Factor ≤ 1.22 W/m²K or
Energy Rating ≥ 34

Most window companies do not commercially make a window with this rating – the customer will pay way more than $125 to get this window.

If they want the $250 grant per opening, the window has to meet the following energy rating:

U-Factor of 1.05 W/m²K or less or
Energy Rating ≥ 40

This can only be achieved by special triple-pane windows that will cost the homeowner significantly more than an additional $250 per window.

These issues are all as a result of Energy Star moving from three rating zones in North America to one Zone. In order to be Energy Star approved your door and window has to perform as well in the Northwest Territories at -50c as it does in lower BC at 10c
