Rivière des Mille Îles
watercourse in Quebec, Canada
The Rivière des Mille Îles (French: [ʁivjɛʁ de mil il], "Thousand Islands River") is a channel of the Ottawa River in southwestern Quebec, Canada and runs into the Rivière des Prairies. It is 42 kilometres (26 mi) long.
It divides Île Jésus (the city of Laval) from the North Shore, the northern mainland suburbs of Montreal, such as Deux-Montagnes, Saint-Eustache, Boisbriand, Rosemère, Lorraine, Bois-des-Filion, Sainte-Thérèse, and Terrebonne.
The river rises at the narrowing of the Lake of Two Mountains, where the Ottawa River widens as it feeds into the St Lawrence at Montreal, and flows west to east. It joins the Rivière des Prairies at the eastern tip of Île Jésus, which shortly thereafter joins the St. Lawrence at the eastern tip of the Island of Montreal.
As its name suggests, the river contains many small islands which are part of the Hochelaga Archipelago. It is not to be confused with the Thousand Islands at the head of the St. Lawrence River, in Ontario and New York State.

Why this record matters
“Rivière des Mille Îles” is worth following because a concise public description often conceals a longer documentary argument. Here, Rivière, Mille and Îles provides the most credible route into that argument.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Aug 31, 2026. The linked authority identifier is Q2130616. VIAF identifies the subject as 315130591. Authority coordinates are 45.699, -73.529. 1 of 3 selected statements include explicit references; 2 carry qualifiers and 0 use preferred rank.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
