Average vs Median vs HPI: How to Read GTA Home Prices
Why the “average sale price” can mislead — and why the HPI benchmark is steadier
Average, median, HPI benchmark — which price should you trust?
Each has a job: the average (all sale prices summed ÷ number of sales) is the usual headline, but it’s easily skewed by a few luxury sales and by changes in the “mix” of homes sold; the median is the middle sale, closer to “what a typical buyer actually paid”; and the MLS HPI benchmark prices a single “typical home” every month, stripping out mix changes — making it best for judging whether prices themselves rose or fell.

Every month a headline “average Toronto home price” appears, and people judge the market from it. But the average is the most misleading of the three common measures. Here is average, median and the HPI benchmark explained — and how, on the same market, all three can tell different stories, using TRREB’s latest real data.

Average: most common, most easily skewed
Median: closer to the typical buyer
HPI benchmark: mix-adjusted, best for trends
ℹ️Next time you see “Toronto average price up/down X% year-over-year,” ask one more question: what did the HPI benchmark do? If the average and HPI differ a lot in direction or size, it’s usually the mix that changed, not the homes themselves.
Three stories from the same market
💡 A simple division of labour: use the average for headlines, the median for “what a typical buyer paid,” and the HPI benchmark to judge whether prices truly rose or fell. When the three disagree, ask first whether the mix of homes sold changed this month.
A ten-sale illustration
Say ten condos sell in a month: $500K, $550K, $580K, $600K, $620K, $640K, $660K, $700K, $750K — plus one $4,000,000 penthouse. Average = $9,600K ÷ 10 = $960,000; median = midpoint of the 5th ($620K) and 6th ($640K) = $630,000. That single $4M sale drags the average to $960K — $330K above the median. Nine of ten buyers paid under $760K, yet the “average” suggests ~$960K. The median ($630K) describes the typical buyer far better — exactly the problem the HPI solves.
Frequently Asked Questions
What’s the difference between average and median price?
The average sums all sale prices and divides by the count, so a few luxury sales pull it up. The median is the middle sale — half above, half below — which resists outliers and is closer to what a typical buyer actually paid.
What is the MLS HPI benchmark?
It’s a price CREA/TRREB compute for a virtual “typical home,” pricing the same typical home each month. It strips out changes in the mix of homes sold, making it best for judging whether prices themselves rose or fell.
Does TRREB publish a median price?
No. According to TRREB (May 2026), the Market Watch reports the average sale price and the HPI benchmark, but not a median. Verify the source of any “Toronto median” figure.
Did GTA prices rise or fall in May 2026?
According to TRREB (May 2026), the average sale price was $1,069,700, down 4.6% year-over-year, while the mix-adjusted MLS HPI Composite benchmark was down 6.7% — the latter better reflects the true price decline.
