Several programs may benefit Renfrew County homeowners. The Canada Greener Homes Loan offers up to $40,000 interest-free for qualifying upgrades including insulation, heat pumps, and windows. The Oil to Heat Pump Affordability (OHPA) program provides up to $15,000 for homes currently heated with oil — particularly relevant for rural properties in Renfrew County. The HST Rebate on Substantial Renovations allows homeowners to recover up to 36% of the HST paid on qualifying major renovation work. See our full grants section for details on all ten programs, eligibility rules, and how to apply.
It depends on the type of work. In Renfrew County, permits are typically required for: new roofing on a structural deck, electrical work (required by the Electrical Safety Authority), new or replacement well drilling (under Ontario Regulation 903), septic system installation or major repair (under OBC Part 8, permitted by the Renfrew County and District Health Unit), and foundation alterations. Cosmetic work such as interior painting or carpet replacement generally does not require a permit. Permit authority varies by municipality — see our Building Permits guide for municipality-by-municipality detail.
In Ontario, the following trades have mandatory provincial licensing requirements:
Painters, roofers, and insulation contractors do not require a provincial trade licence in Ontario, though some municipalities may have local business licensing requirements. Always verify credentials and request proof of liability insurance regardless of trade.
Yes, in many cases programs can be stacked. For insulation upgrades, the Canada Greener Homes Loan can be combined with the Ontario Home Efficiency Rebate Plus (HER+) program in many scenarios. For homeowners converting from oil heat, the Oil to Heat Pump Affordability (OHPA) grant can often be combined with the Greener Homes Loan for a heat pump installation. The HST rebate on substantial renovations applies to qualifying renovation costs broadly and does not preclude other programs. Program stacking rules change — see renfrewcountyhomeservices.ca/grants/ for current guidance and links to official program pages.
