In the case of major infestation, a temporary permit is required. Please call Public Works at 514 630-2727 and an employee will come onsite to evaluate the situation and issue a permit valid for 10 days from the issue date. Major infestations include the presence of insects, mold or other harmful agents, except for weed, that have spread over 50% of a property or more than 5 m2 of a garden's surface. Infestations must be a human safety or health hazard, or pose a threat to the survival of trees and shrubs or animal life.
