@ Bob, why don't you ask the original poster over on Canadian Gun Nutz? There is chatter there, which I have not followed closely, and the suggestion that there were a few batches of WP vehicles imported.
BTW, if anyone maintains a website of Canadian vehicles and modern military history, these conversations represent a good foundation for a webpage. There are photos and captions with first person narratives of using T72 vehicles as trainers and OPFOR against Canadian Leopards. Snag things while they are available. Never know when the host sites will go down ...
