Ottawa drew a line at one million dollars. For once, the line sits above where Alberta builds rather than below it.
GST relief for first time home buyers is now in effect. Bill C-4 has received Royal Assent and the mechanics fit in three sentences. On a new home priced under $1 million, the federal sales tax comes off entirely. On a new home between $1 million and $1.5 million, the tax is reduced rather than eliminated. Above $1.5 million, nothing changes at all.
There is a timing condition attached, and it is the detail most likely to catch people out. The agreement of purchase and sale has to be entered on or after March 20, 2025, and before 2031. A buyer who signed a week before that window opened is outside the measure entirely, holding the same house at the same price with the full federal tax still on it.
Why the threshold matters more here
A single national threshold does very different work depending on which province you are standing in.
In Calgary and Edmonton, a ceiling of $1 million sits comfortably above the typical new build. That means full relief, not the partial band, on the great majority of what gets framed in this province. In markets where new homes routinely price above the cutoff, the same measure reaches a much narrower set of buyers, and a share of what is left falls into the reduced band between $1 million and $1.5 million rather than the full exemption.
None of that was designed as a favour to Alberta. It is the arithmetic of applying one number to a country with wildly different housing costs, and Alberta happens to land on the useful side of it this time. That is unusual enough to be worth saying out loud.
It is also evidence of something less flattering. A threshold that works cleanly in one province and awkwardly in another was not built with either province specifically in mind. It was built for an average, and nobody actually lives in an average.
A threshold left sitting since 1991
The GST thresholds on new housing had not changed since 1991. Over the same period the New Housing Price Index has more than doubled.
That single pairing explains most of what went wrong with this tax. Nobody in Parliament ever stood up and voted to increase the tax burden on new housing. They did not have to. The number in the statute stood still while the price of the thing being taxed climbed past it, and the effective burden rose year after year without a debate, an amendment or a single line in a budget speech.
Bill C-4 fixes the level. It does not fix the mechanism. The new thresholds are set at $1 million and $1.5 million and, as written, they will sit exactly where the old ones sat until some future Parliament decides otherwise. Absent indexing, the same erosion starts again from a higher base, and somebody will be writing this same analysis a decade from now with different numbers in it.
Alberta knows the pattern from other files. A number set for the country of 1991 keeps governing a country that has moved on, and the question of when Ottawa will treat Alberta like a partner runs on the same logic. The figure was reasonable once and nobody was ever obliged to revisit it.
How many buyers this actually reaches
Now the limitation, and it is a substantial one. First time buyers make up 5.8% of new home purchasers.
That figure sets the ceiling on what this measure can do. Relief written for first time buyers alone reaches roughly one purchaser in seventeen. The other 94.2% pay the federal tax exactly as they did last week. Move up buyers with a growing family. Downsizers selling a house that is now too much to maintain. Workers relocating into Alberta who owned somewhere else before they got here. Every one of them is outside it.
The building industry has been direct about where it would rather see this go. Kevin Lee, chief executive of the Canadian Home Builders’ Association, has pointed to GST relief extended to all buyers and to development charge relief as the measures that “are at the top of that list.”
That is a builder asking for a bigger version of what just passed rather than a different policy. The measure works. It simply works for a small share of the people buying.
What to watch from here
Three things are worth tracking. Whether the new thresholds are ever indexed, because the answer determines how long this relief stays meaningful. Whether eligibility is extended past first time buyers, which is the change the industry keeps pressing for. And what happens as 2031 approaches, because a measure with an expiry date starts shaping buyer behaviour well before the date arrives.
For now, Alberta buyers are working with a federal housing measure that happens to fit this market better than most federal housing measures fit it. Use it while it is there. And keep the 5.8% in mind, because it is the honest measure of how much of the affordability problem this actually touches.
Should GST relief on new homes be extended to every buyer rather than first time buyers alone?
