The company was founded in 1959 in Jonquière, but expanded greatly in 1990 with the acquisition of Voyageur's routes in the Saguenay–Lac-Saint-Jean region and the North Coast of the Saint Lawrence River.

The next step in the evolution of the Intercar Group, already well established in student transportation in Saguenay-Lac-Saint-Jean, was the launch of school bus services in the area around Quebec City.

Further expansion of their interurban routes to Sept-Îles meant that by 2001 they dominated those services in the triangle between Sept-Iles, Dolbeau and Quebec.

Throughout the early part of this century they have continued to acquire more school transportation companies and further grow their charter service.
