I have been to Montreal many times. It does get dark still? Hard to tell what it is like outside down in the tunnels.
Things like moth species and others love moist leaves to lay eggs and they only work at night. Again, anywhere, avoid watering late in the day unless you have to do so. Why tempt fate? There is no sunlight to evaporate water at night and could even be a dew point to aggravate things?
