Learn MoreCedrus is the Latin name for the cedar tree — the same cedar of Lebanon that stands at the centre of the Lebanese flag. For founder Mario Keedy, the name is a tribute to home: a tree known for its strength, its patience, and its ability to stand for centuries without losing its shape.
Mario built this company on that same idea — that good construction, like good wood, needs a strong grain, an honest structure, and the patience to be done properly. That's the standard behind every renovation, addition, and outdoor space we build in Ottawa.
