Donat Asselin Outfitter, winter only. No fuel. Phone (418) 661-0580. Fax (418) 664-1881. Website:

Km 528 LA-2 airport.
Km 542
Somewhere around here you will be the farthest north you can reach in eastern Canada along a road, except for the rougher stretch of the Trans-Taiga Road east of Brisay - there the road goes even farther north.

Km 582

Brisay dam and generating station. At this point you are 658 km from the nearest town (Radisson)!
Hydro Quebec residences, not open to the public. No services or accommodations.
There's an extensive set of Hydro Quebec interpretive signs here, along a small self-guided road tour of the hydro installation, including a high viewpoint. Well worth a visit, especially after driving all this way. No tours are available.
The road from Brisay to Caniapiscau is rougher and a 4-wheel drive vehicle is recommended by Hydro Quebec. The main reason for this is the very coarse gravel used for this road - there's large rocks littering the road surface - and the dips in the road. However, I have heard from people who have driven this road in ordinary passenger cars and they say it is fine. You do have to keep your eyes open for the larger rocks though. However, the road becomes more scenic and rises in elevation (up to about 2000 feet above sea level).
-->To continue to Caniapiscau, when coming in to the Brisay area, turn right at the "T" junction, follow the signs to the "Belvedere", then turn left at the signs for "Belvedere" and "Caniapiscau" (the sign for Caniapiscau indicates that it is 92 km away, but all other sources say that the Trans-Taiga Road ends at km 666, which is 84 km away). Continue straight, over the control structure past the "Belvederes". There are no further signs indicating that this is the road to Caniapiscau.

Road splits here. Right branch goes to the Caniapiscau dam (very interesting place). Left branch goes to Air Saguenay base on Lac Pau and then to the garbage dump for the area.
