I am not sure that either though regarding larger amounts of money transfer to Canada as PR and if it will be taxed, but you can easily find information on websites of larger Canadian banks such as RBC or BMO. I myself did find very useful information on taxation and fianance regulations across Canada on RBC, Royal Bank of Canada (
www.rbc.com) that also offers a very reliable package of finances for new immigrants.
But somehow or another, the tax you might pay over any amount of money, will be far far far far less than that here in EU. :-)
