cnovosel,
I'm afraid I don't have any specific guidance about getting the Canadian license but...I did remember that your "based-on" FAA PPL (FAR 61.75, I assume) cannot be used to get a TCCA license via the FAA-TCCA agreement governing this. So that option apparently isn't available. Too bad as it would perhaps simplify things. See Section 13a(1)c:
"The license must not have been
issued on the basis of another foreign license (see subparagraph 7a)."
