Where can I find Canadian tornado data and information?

The ECCC/MSC Library at the Downsview facility in Toronto holds all of the country’s physical tornado archives including reports, event summaries, maps, newspaper clippings, photos, slides, video and film. This material is in the process of being digitized and some will soon be available online on our website.

The NTP website is also a source for recent tornado data and includes interactive mapping, access to damage photos, drone video, and aerial imagery.

On the Government of Canada Open Data portal, tornado data compiled for the period 1980-2009 can be found in multiple formats here.
