This page lists the biggest rainstorms or snowstorms of the year in Montreal, Quebec Canada along with the date they occurred. The information answers questions like: When was the last time more than 70 millimetres of precipitation landed on Montreal in a single day? What was the rainiest day of 2017?

The list gives the highest daily precipitation for each year in Montreal and the date that it happened. A date with a plus sign beside it means the same amount of moisture also fell on at least one other day earlier that year.
