I'm not sure of the grand total, but most of the cities where TWI operates have about 20-50 people. (Toronto, London, and Montreal have the biggest groups, as far as I know). So I'd say it would be a little under 200? There was a country meeting not so long ago in Ottawa and a little under 100 people showed up, but I don't know if it's an accurate representation of the numbers because of travel/hotel space/money/timing.
