Buying waterfront in Ontario
Waterfront covers everything from year-round lakefront houses and riverside condos to seasonal cottages. In Ontario the deepest waterfront inventory is in cottage country: the Kawarthas, Muskoka, Prince Edward County, and the Rideau system, with a smaller supply of urban waterfront in cities like Toronto and Ottawa.
When comparing waterfront properties, look closely at shoreline ownership and any shore road allowance, year-round road access, water source and septic condition, and whether the home is winterized for four-season use. Insurance and financing can also differ for seasonal properties, so confirm both early.
Every listing on this page carries a verified waterfront designation from its MLS® listing data, refreshed daily.
