What was the weather like this week, last year?

I need to be able to get a sense of what the weather was like, this week, last year. I need to be able to look up major Canadian cities.
I don't need to see weather by the hour, or rain by the millimetre. Ideally, just something that shows me that it was hot, or rainy or snowy or cold , with a graph or something visual would be nice. Can you recommend such a website?

Environment Canada will give you a monthly summary of weather data for any station you like. Here's March 2024 in Ottawa. You can get to this by doing a historical data search and then selecting Daily data (March 2025) and switching the year to 2024 or you can simply change the station id in the first URL.
This won't usually differentiate between snow and rain and it isn't a pretty graph, but it does get you the data that you want.

Weatherspark past weather search.. Type in the city you want, then pick the year and month from the top of the page you get.

as someone who used to use historical Canadian weather data as their job, ssg's Environment Canada link is the source. Everything else is derived from that, and sometimes with questionable quality.
The graph that tells you what normal was for a particular time (so you can see if a particular day was wetter, or colder, etc) comes from the Climate Normals, f'rinstance Temperature and Precipitation Graph for 1991 to 2020 Canadian Climate Normals: MONTREAL TRUDEAU (AIRPORT). For a particular day or month across time, you want the Almanac Averages and Extremes. Here's what it did today in Sudbury from 1954-2013: Almanac Averages and Extremes for March 10.
Note that the historical data takes several years to check and correct, so if you're looking for recent-recent, you're out of luck. No idea where the other sites get their data.
