I recently encountered someone allowing his dog to run loose along the Boundary Bay dike and trail where migratory birds stop over during their migration.
When I told him that no off-leash dogs were allowed in the area, he said his dog was looking for coyotes and was allowed to roam offleash as he was working for Metro Vancouver's coyote control.
I contacted Metro Vancouver and inquired if it had such a program in place and received this reply from Karl Winkler, park operator, Metropolitan Planning Environment and Parks:
"Metro Vancouver staff enforces the leash bylaw on the Boundary Bay dike trail not the land adjacent to it; that is under the jurisdiction of the Ministry of Environment; we do not have any official designated off-leash area and have no such mentioned program ("coyote control").
"Our staff patrols Boundary Bay park trails daily and the East Delta dike on a weekly basis. It is our goal for visitors to enjoy the protected environment and treat it with respect."
