The St. Lawrence runs from Kingston past the Thousand Islands through Brockville, Prescott, Morrisburg and Cornwall — a working shipping seaway with international traffic through the Iroquois and Eisenhower locks. The islands from Gananoque to Rockport are the classic cottage stretch; Brockville and Prescott carry more full-time year-round homes on the mainland. Water levels are seaway-managed and shoreline is often deep.
This page shows every active detached and semi-detached home on the St. Lawrence River in Ontario, including the islands. Because the river is navigable commercial water, dock configurations and shoreline protection matter more than on interior lakes — check the card details. Marina-only and shared-access listings are excluded.
How this page decides what counts as waterfront
Only detached and semi-detached homes appear here. Each one shows some evidence of genuine water frontage — a dock, boathouse, boat slip, private beach, or direct water view. Waterfront condos and townhomes on St. Lawrence River are excluded on purpose: the MLS waterfront fields on a condo describe the building, not the unit, and mixing them in misrepresents what you're buying. Deeded-access shares, road-between lots, and marina-only slips are also excluded.
Ownership, shoreline, and access
Ontario waterfront has three moving parts every buyer eventually has to understand: who owns the shore road allowance (Owned, Not Owned, None, Partially Owned — cards note this where available), what the shoreline itself is (sand, natural, rocky, weedy, hard bottom), and how you reach the property (year-round municipal road, seasonal road, water access only). None of these are dealbreakers on their own; they change the price, the mortgage, and the insurance conversation.
Common questions
What counts as a genuine waterfront home on St. Lawrence River?
Detached or semi-detached homes with real water frontage — a dock, boathouse, boat slip, direct water view, private beach, or similar. Waterfront condos and townhomes are excluded because their MLS waterfront fields describe the building, not the unit.
Does "None" for shoreline allowance mean there's no shoreline?
No — it means there is no shore road allowance strip between the lot and the water, which is good. "Owned" means the seller bought that strip. "Not Owned" means it belongs to the municipality or Crown. All three states can appear on a genuine waterfront home; this page does not filter by any of them.
How many waterfront homes are for sale on St. Lawrence River right now?
76 active detached and semi-detached waterfront homes on St. Lawrence River at the time this page was last updated. The live grid above fetches current inventory on every page load.
Can I book a viewing without a real estate agent?
Yes. Every listing card has a Book a viewing button that reaches Faisal directly. He'll walk you through what the listing actually offers — shoreline, dock rights, road access, water depth — before you drive out.
