Parc Extension (usually shortened to Parc Ex) is a long rectangular neighbourhood in the North-East portion of Montreal’s downtown core, and part of the larger Villeray-St-Michel-Parc-Extension borough. Geographically, it stretches between Acadie Boulevard, splitting its streets off from the Town of Mount Royal next door, and the train tracks to by Jarry Park. North to South, it stops at Highway 40 and Beaumont Avenue.
