Trees & Fences Bylaw 08-2011 (To prohibit obstructions adjacent to certain road allowances) regulates the setback distances of “obstructions” (trees, fences, snow piles, etc.). Trees and fences must be placed 150 feet from the centerline of a road or 300 feet from the intersection of two roads. A barbed wire fence is not considered an obstruction so it may be placed on the property line (subject to requirements The Stray Animals Act).
