Waterfront homes for sale on the Ottawa River
95 active waterfront homes on Ottawa River · updated August 23, 2026
The Ottawa River forms the border with Québec from Mattawa in the north through the Ottawa Valley to the confluence with the St. Lawrence at Île Perrot. Waterfront homes concentrate around Deep River, Petawawa, Arnprior, Constance Bay, Cumberland and the Rockland shore — plus the eastern reach through Alfred, Hawkesbury and Chute-à-Blondeau. The river runs a full-scale hydroelectric system so water levels are managed, not seasonal like the interior lakes.
This page shows every active detached and semi-detached home on the Ottawa River in Ontario. The river is wide enough here that most listings read like lake-front homes rather than river-front — big open views, deep water, real docks. Marina-slip and deeded-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 Ottawa 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
Waterfront homes take patience and a straight-talking view of shoreline, dock, and access rights. I'll walk you through what's actually being offered before you drive up to Ottawa River.
