It wouldn't necessarily be any police force in Canada, but certainly most of the large police departments, yes, and many small ones. I'm not trying to pick on the small ones, but some police departments are a little more advanced than others in terms of training. So I would be a little more cautious on who, but once there was an agreed-upon training standard, with approved instructors, that could be done.
