It is typically illegal to disturb a bird’s nest with eggs or chicks inside. The best solution is to wait a few weeks until the babies grow up. If there is a nest in an area that causes problems (above a building entrance, in a vent) you may need a permit from Environment Canada to move the nest legally.
