Fulfillment, AI underwriting, and viral marketing for mortgage agents and brokerage owners across the Thunder Bay area — so a small team can keep pace with one of Ontario’s last true sellers’ markets.
Thunder Bay remains an outlier among Ontario markets. While much of the province cooled through 2026, the Thunder Bay Real Estate Board reported single detached home sales up 7.3% year over year in March, to 59 units, with the median sale price climbing 5.4% to $398,000. Board president Karen Hill has described it as a persistent sellers’ market with multiple offers still common on new listings — a dynamic most of Ontario left behind years ago.
A tight, competitive market like Thunder Bay’s puts a premium on speed: a broker who can turn around underwriting support and conditions fastest keeps the file. That same speed matters for the roughly ≈1.15M Canadian mortgages renewing in 2026 — in a market where clients still have leverage, being first to reach them with a renewal or switch-and-save option, ahead of their existing lender, is often the difference between keeping a client and losing one.

The underlying household economics of the Thunder Bay CMA, straight from the 2021 Census.
The Thunder Bay CMA was home to 53,535 households in 2021. 70.4% owned rather than rented — above the 66.6% national rate — and 52.9% of those owners still had a mortgage outstanding, below the national 60.0%. In absolute terms that is 19,955 mortgaged owner households.
On income, the Thunder Bay CMA median was $80,000 in 2020 against $84,000 nationally — 5% below. What matters more at qualification is the shelter-cost ratio: 13.2% of owner households with a mortgage were at or above the 30% threshold, below the national 20.9%.
Read commercially: 19,955 households in the Thunder Bay CMA hold a mortgage that will eventually come up for renewal, and the 13.2% already stretched past 30% of income on shelter are the ones with the most to gain from a switch. Finding them before their lender's renewal letter does is the whole game.
