The Cobourg market right now

Cobourg is the largest town in, and seat of, Northumberland County, its population up 5.6% to 20,519 since 2016. Its Lake Ontario harbour made it a 19th-century commercial and rail centre; today the town markets itself around its restored waterfront, marina, and beach, supporting real premium-property demand alongside everyday purchase activity. The age profile skews older than the provincial average — residents 65 and up make up 21.1% of the population — consistent with Cobourg’s position as a lakeside retirement and commuter town roughly 95 km from Toronto. Central Lakes Association of REALTORS® data for the Northumberland County region (shared with Port Hope) show 152 home sales in June 2026, up 18.8% from May’s 128, with an average selling price of $677,570, down 2.6% from May’s $695,364.

That combination — waterfront premium properties, a large retiree population, and Toronto-commuter demand — makes for a file mix that spans downsizing, second-home, and relocation mortgages all at once. With roughly 1.15 million Canadian mortgages renewing across Canada in 2026, a meaningful share of Cobourg’s older client base is likely facing renewal decisions right alongside younger commuter buyers entering the market for the first time.

The Cobourg household picture

Census figures for the Cobourg CA — the base your renewal and purchase volume is drawn from.

Median household income (2020)
$77,000
National median $84,000
Homeownership rate
68.8%
Canada 66.6%
Owners still carrying a mortgage
47.4%
Canada 60.0%
Mortgaged owners at 30%+ of income on shelter
21.0%
Canada 20.9%

At the 2021 Census the Cobourg CA counted 9,120 households, 6,270 of them owner-occupied — a homeownership rate of 68.8%, above the national 66.6%. 2,970 of those owner households were still carrying a mortgage, or 47.4% of all owners against 60.0% nationally.

Median household income was $77,000 in 2020, 8% below the national median of $84,000. On the shelter-cost side, 21.0% of mortgaged owner households here were already spending 30% or more of household income on shelter, essentially level with the 20.9% national share.

For a brokerage those 2,970 mortgaged owner households are the addressable renewal base in this market — and the 21.0% already at or past the 30% shelter-cost threshold are the files where repricing at renewal bites hardest. Those are the conversations worth reaching first.
