5 Things You Should Know About Ontario’s Massive HST Rebate Expansion (Up to $130K Off New Homes)

Ontario and the federal government have just supercharged the HST rebate on new homes and it’s perfectly timed for anyone planning a build in the province. Effective April 1, 2026, to March 31, 2027, you can now claim the full 13% HST back on homes priced up to $1 million (max $130,000 savings). Even on homes up to $1.5 million you still get the full $130K; it only tapers after that.

This isn’t just for first-time buyers anymore — any eligible buyer using the home as a primary residence or rental qualifies. Ontario covers the 8% provincial piece, Ottawa handles the 5% GST, injecting $2.2 billion into the market and forecasting 8,000 extra housing starts plus 21,000 jobs next year.

Prefab and modular homes qualify exactly like site-built ones, freeing up serious cash for better finishes, energy upgrades, or faster lot prep.

Here are the 5 key takeaways:

• Up to $130K straight back in your pocket — Full rebate on homes ≤$1M; still $130K max up to $1.5M. Real money that drops your prefab package cost immediately.
• Open to everyone who qualifies — Primary residence or rental. Not just first-timers. Families, investors, and down-sizers all win.
• Prefab gets the same love — Modular builds count 100%. Lower tax = more budget for the custom design you actually want.
• Combined power move — Pair it with the new development-charge cuts and builders are already saying you could see up to $200K total relief. One prominent Ontario builder called it “the kind of policy that moves the needle on housing supply.”
• One-year window only — Purchase agreement must close in this period or you miss the max savings. Act fast.
