How Much Does a Ontario Green Savings Contract Really Cost?
The monthly fee on a Ontario Green Savings agreement is the visible number. The cumulative obligation over the life of the contract is the number that matters — and the gap between that number and the equipment's true value is what makes these contracts challengeable.
The two numbers that matter
- The monthly figure on the statement — visible, easily ignored.
- The cumulative obligation over the life of the contract — usually striking when added up.
For most Ontario HVAC, water heater, heat pump, and air filter contracts, the gap between the cumulative obligation and the equipment's true installed value is several multiples — often 5× or more.
Typical contract structure
- Term lengths of 10 to 15 years (sometimes longer with renewals)
- Total obligations frequently between $20,000 and $40,000+ for equipment that retails for a small fraction of that figure
- A registration (Notice of Security Interest, or NOSI, prior to the 2019 ban) on title or a similar lien against the property
- Agreements often assigned to a separate finance company, so payments are collected by a different entity than the installer
- Buyout clauses that grow more punitive the longer you stay in the contract
What the cost gap means legally
Where the cumulative Ontario Green Savings contract obligation is grossly disproportionate to the equipment's installed value, the unconscionable-pricing ground in the 2018 amendments applies directly. This is among the cleanest grounds for setting an agreement aside.
Cumulative cost is the story
When homeowners pull their statements together for the first time and see the cumulative number, that is usually the moment they realise something is wrong. The cumulative figure is also the starting point for any damages estimate — see our four pillars of damages guide.
