St. Catharines is the largest city in Niagara, set between Lake Ontario and the escarpment on the Welland Canal, at the centre of Canada's best-known wine region and a half-hour from the American border. It has long been the affordable alternative to the western GTA.

The Niagara Association of REALTORS® covers the whole Niagara region but publishes a dedicated St. Catharines line in the table by municipality of its monthly stats package, so the figures above describe the city itself rather than a regional number standing in for it. Reading change over time from that table calls for care: a year-over-year percentage computed from two published points looks authoritative but silently assumes the board did not revise its earlier figure — and boards revise routinely. For a decision of this size, a raw pair of numbers with a date on each is worth more than a tidy percentage with a hidden assumption inside it.

Frequently asked questions
How much does a home cost in St. Catharines in 2026?
In July 2026, the MLS® benchmark price in St. Catharines stood at $528,500. Source: Niagara Association of REALTORS® (NAR), July 2026.
Why can a year-over-year percentage computed from two board figures mislead?
Because it silently assumes the earlier figure was never revised — and real estate boards revise routinely. Two published figures, each with its date, are a more honest basis for comparison than a percentage calculated from them, which is why reading them side by side with a local professional is the safer approach.
How long does it take to sell a home in St. Catharines?
Homes in St. Catharines took an average of 39 days to sell. Source: Niagara Association of REALTORS® (NAR), July 2026.
How active is the St. Catharines market?
In July 2026, there were 150 sales in St. Catharines. Source: Niagara Association of REALTORS® (NAR), July 2026.
Do these figures cover only the city of St. Catharines?
Yes. The board covers the whole Niagara region but publishes a dedicated St. Catharines line in its monthly table, which is what appears here — not a regional figure standing in for the city.
How much tax do you pay when you sell a home in St. Catharines?
Usually none if it is your principal residence: the Canada Revenue Agency's principal residence exemption wipes out the capital gain for each year the home is designated, though the sale must still be reported. For another property (cottage, rental), half the gain is added to taxable income (1/2 inclusion rate, CRA guide T4037) and taxed at your marginal rate. Example at St. Catharines's reference price ($528,500): bought for $428,500, the home shows a gain of $100,000: $0 taxable if it is your principal residence; otherwise $50,000 of taxable amount is added to your income (the resulting tax depends on your marginal rate, not computed here). The land transfer tax is paid by the buyer, not the seller; the agent's commission is negotiated, and no official schedule sets it.
