Not really much helpful but it does have some commercial bits, such as the recent Freeman/St-Joseph strip mall. Not sure if the Tasse group will do a lot of new projects in the future. They mostly cover the areas along the Gatineau River such as Touraine and Pointe-Gatineau and it is mostly for existing appartment buildings/condos.
