The mountain range in Canada that is considered an extension of the Appalachians is the Laurentian Mountains.

Located in Quebec, the Laurentians are part of the larger Appalachian Mountain system that extends into Canada. This range features a mix of rugged terrain, forests, and lakes, and it plays a significant role in the region's ecology and outdoor recreation. The Laurentians are known for their stunning landscapes, skiing resorts, and vibrant fall foliage, attracting visitors year-round. Their geological similarities to the Appalachian Mountains further emphasize the interconnectedness of these mountain ranges across the North American continent.
