Check out this Canadian government website, see link below, which lets you select whatever weather data you wish to collect from 1840 - 2017. You can narrow down your search to specific areas, or collect for the country overall.
You will find most governments have done this for many years, and are now making this data freely available for researchers to use.
You could also check out the CRU dataset: https://crudata.uea.ac.uk/cru/data/hrg/cru_ts_3.24.01/cruts.1701201703.v3.24.01/pre/, but it is at fairly coarse resolution.
