Hi hkahloon,
I am also in the same boat as you! I am still in the early stages, but these are the things that I learned so far:
For EE, you need your educational credentials to be evaluated by WES (which is faster than the CAPR) - this would give you Bachelors equivalency if you had your PT in Bachelors degree as entry level. If you have higher studies, this could potentially boost your CRS score. You will only use WES (or other approved agencies) for your EE profile.
As PT is a regulated profession in Canada, you need to apply for licensure.
Concurrently, you need to have your education assessed by CAPR (a must for licensure). This would take about 3-4 months to complete once they received all the requirements. You would need to take additional course (1-2 months) regarding Canadian healthcare system, and you would need to take TOEFL or IELTS Academic Module (overall score of 7 is required) as additional requirements. EE requires IELTS GT only, so your would need to take IELTS at least twice (A / GT). This would give you the eligibility to take the PCE, if quailfied (written, then practical exam). It is a long process to be a PT in Canada, but generally, it is doable.
If you qualify for express entry, I would assume you could come to Canada and work as a PTA temporarily (depending on the province), while working on your PT license (taking the PCE - as it is only offered a few times in a year).
For other PTs out there, please share your experiences.
