Hi Slegs,
Check out the web-site for the Canadian Alliance of Physiotherapy Regulators.
http://www.alliancept.org/
This gives information regarding credentialing process, and then look at the Physiotherapy association or College for the province you are interested in registering in.
Each province has it's own rules and requirements, but most require you to pass the Alliance's competency exam, which you can only challenge having had your credentials examined for equivalency to Canadian training first.
