Default Re: All Ontario Confirmed & Probable Tornadoes

These lists and maps can now only be used as general guidance as to what these numbers may look like. After a lengthy several month long investigation, several Environment Canada and National Weather Service data sources are not aligning. An extreme case has been uncovered in Hamilton where three different Environment Canada sources are confirming three different tallies for two segments panning 1979-2004 and 1984-2001 and also the original 1792-2009.
