The rundown
Montreal sits at the exact spot where the St. Lawrence and Ottawa rivers crash into each other, splinter around two islands, and throw off rapids that surfers actually ride in wetsuits in the middle of a landlocked Canadian city. Most people who live within ten minutes of this never once get in a boat. Here's the case against that.
H2O Adventures — Lachine Canal Nautical Centre

2727 Rue Saint-Patrick, behind the Atwater Market, steps from the Lionel-Groulx metro. This is the easiest entry point in the city: rent a kayak, a paddleboard, or one of their electric boats and paddle the calm, glassy water of a 19th-century industrial canal that bypassed the Lachine Rapids back when the rapids were a shipping problem instead of a tourist attraction. The Old Port sits at one end of the paddle, Saint-Henri's converted factories line the other.
What we're doing: Single kayak, evening slot after 6pm when the light goes gold on the old grain silos, paddle to the Old Port and back before the locks close.
KSF at Parc des Rapides

End of Boulevard LaSalle, LaSalle borough. This is where the real river shows its teeth. The Lachine Rapids at Parc des Rapides draw a real community of river surfers who know the standing waves here by name: Big Joe, Gaétan, the Pyramidal. KSF rents surfboards, paddleboards, and kayaks right at the park, and the current here is genuinely strong enough that this isn't a lazy-Sunday rental, it's a legitimate whitewater scene hiding in a residential borough most tourists never visit.
What we're doing: Rent a SUP, stay in the eddy line near shore until you've clocked how fast the current actually moves, then decide if Big Joe is happening today.
Parc de la Rivière-des-Mille-Îles

345 Boulevard Sainte-Rose, Laval, about 25 minutes north. This is Montreal's largest kayak and canoe rental operation, and it's built around a river system that splits into so many channels and marshy islands that a two-hour paddle can feel like it covers real distance without ever touching a current strong enough to worry about. Bird life here is dense, herons and osprey working the reed beds, and the whole thing reads more like cottage country than a suburb 25 minutes from downtown.
What we're doing: Tandem canoe, the marked interpretive route through the islands, binoculars if anyone in the group actually owns a pair.
Parc-nature du Bois-de-l'Île-Bizard

2115 Chemin du Bord-du-Lac, Île-Bizard, far west end of the island. This is the option nobody thinks about because it's a genuine haul from downtown, 35 to 40 minutes depending on traffic, but the payoff is a nature park with its own beach, marsh boardwalks, and canoe rentals on a lake calm enough for total beginners. The marsh trail alone makes the trip worth it even without getting in the water, turtles sunning on logs close enough to actually see without binoculars.
What we're doing: Canoe rental at the beach kiosk, paddle the marsh perimeter slow, swim at the beach after to actually justify the drive out.
The Pattern
Every one of these five spots takes the same river and shows a different mood of it: industrial-calm at the Lachine Canal, genuinely wild at the Rapids, suburban-quiet at the Mille Îles, forgotten at Île-Bizard. Montreal never had to build a lake district or bus people to the coast. It just had a river running through the middle of an island city that decided, at some point, to actually use it instead of just crossing it on a bridge.
