The Mille-Îles River is over 42 km long. It allows the Ottawa River and the Lake des Deux-Montagnes to flow into the St. Lawrence. The Abenaki named it Makigôteckw River. Near Île-des-Moulins, there's a sanctuary where it is possible to observe more than two hundred different species of birds. Ducks, Canada geese and great blue herons are just a few you can see during the year.
Many activities are offered on the Mille-Îles River: kayaking, canoeing, rabaska, pedal boats, etc. A rowing club offers departures at Parc de la rivière in Terrebonne and Groupe Plein Air Terrebonne offers rentals of various types of boats. The Mille-Îles River is also crossed by La Route Bleue, a navigable route of 155 km, starting on the Ottawa River and ending near Repentigny.
WHAT ACTIVITY IS PROHIBITED ON THE RIVER BETWEEN APRIL 1ST AND JUNE 30TH OF EACH YEAR?
Around Terrebonne, the Mille-Îles River is a unique fish sanctuary. Many species can be found here such as bass, catfish, northern pike, copper redhorse, sturgeon and perch. It is very important to control fishing in order to avoid compromising the ecosystem of the river. This is why it is forbidden to fish in the section located between the Highway 25 bridge and the Quebec-Gatineau railway bridge, from April 1st to June 30th (offenders risk a fine of up to $500). Note that at all times it is prohibited to fish for copper redhorse.
Before leaving for the next stop, look at the river on the left. You will see a few hundred metres away the Sophie Masson Bridge. Don’t forget it as you may find it useful later.
