Now that winter is here, are you feeling the drafts whistling through your doors and windows? You can do more than throw on an extra sweater and avoid the basement – new incentives have just been announced through the Green Ontario Fund (GreenON) to help make your home more comfortable and energy-efficient. These are on top of existing GreenON programs to get a free home energy audit and smart thermostat, which kicked off this summer.

Drafts and leaks don’t just lead to hefty energy bills, they also increase your carbon footprint and contribute to climate change.  In Ontario, almost one quarter of our total greenhouse gas emissions come from heating, cooling, and lighting our buildings. To meet the province’s climate targets, this needs to drop quickly. Not just for new buildings, but for the old creaky ones too – the one’s with lots of character.

Here’s a quick roundup of the new incentives, and how to get the most bang for your home retrofit buck.


Sealing and Insulation: Improving your home’s building envelope

Home energy efficiency isn’t just about upgrading your appliances; it’s also about keeping outdoor temperatures from getting inside and comfortable indoor temperatures from leaking out.

Air leakage around doors, windows, vents and electrical outlets can account for up to 25 per cent of your total heating costs. In fact, air sealing one of the most cost-effective, quick, and important things you can do to make your home more energy-efficient. Caulking and weather-stripping windows, doors, dryer vents, and other areas where air is escaping can offer huge savings, and make life a whole lot more comfortable.

Improving your home’s insulation is another great way to stop heat (or cool air in summer) from flying out the door, wall, ceiling, or floor. Good insulation keeps your home warmer in the winter and cooler in the summer, meaning your heating or cooling system doesn’t have to work as hard.

According to insulation experts at NAIMA Canada, “the attic and basement are good places to start, because those areas represent as much as 15% – 30% of your home’s overall heating and cooling losses. Upgrading insulation levels is one of the smartest energy saving investments you can make.”

You can now get a rebate of up to $7,200 to upgrade insulation in your attic, basement and exterior walls.



Before choosing to entirely replace your windows, you may be able to simply improve the ones you already have.  Adding window treatments or coverings can reduce heat loss, and so can caulking and weatherstripping. You can install insulating window shades, add clear plastic film to the inside of your window frames to reduce drafts, or at the very simplest, reduce heat loss by closing your curtains at night to protect against cold drafts, and opening them in the daytime to let in warming sunlight.

If you’re looking to entirely replace your current windows with energy-efficient ones, look for the ENERGY STAR symbol on home products to make sure they’re certified as energy-efficient. You can now receive incentives of $500/window, up to a total of $5000, to upgrade to high-efficiency windows.


Heat Pumps and Geothermal

Once you’ve sealed up the drafts, it’s time to beef up your heating and cooling systems. Heat pumps are a little-known but very effective way to move freely-available heat to where it’s most needed.  The system can also run in reverse in summer, extracting heat from inside and releasing it outside. You can now get up to $5,800 to install an air-source heat pump in your home.

Geothermal heat pumps (also known as Ground Source Heat Pumps) are a particularly exciting technology, using the constant temperature of the earth just below your home to balance the more variable temperatures above ground. In a nutshell, the earth is used as a heat source in winter, and a cooling source in summer. You can now apply for up to $20,000 in rebates for an ENERGY STAR® Certified ground-source heat pump which can save you up to 50 per cent on home heating costs.









If you’re starting on a home energy retrofit adventure, make sure to start with a free home energy audit to see what your home needs most, and check out all the potential incentives at before you begin.  Every home is different, so it’s important to find the right solutions to maximize your impact.
