I think the credential can only be done in the alliance office in Canada.
I did the credentialing via mail but I registered in Ontario, here is my schedule.
March - April 2007
Sent application form for credentialing with all the documents required
(e.g. IELTS report, Academic report, birth certificate ....., details you can check on the alliance website)
During this period, I was in Hong Kong
It may take up to 22 weeks to complete the credentialing process

I arrived at Toronto.
My credentialing was completed, it said that I did not have experience in working in Canada and I needed to go thru the PLAR in which I chose a self-study package for learning about the Regulation of Physiotherapy in Canada
