Could be wrong, but I think the OP is asking if the cutoff for minimum down payment without insurance will be reduced to 15%, and if longer terms for the mortgage amortizations (like in the States) - 50, 100yr etc. will be coming to Canada.
I would say no to both.
Just last year the maximum mortgage amortization allowed in Canada was decreased to 35 yr from 40 yr.
If I'm wrong, and you are referring to the term of the mortgage with the lender, then yeah, 10 yr terms seem to be the longest, but they are offered by most of the big 5 banks, I know CIBC, RBC, TD, and Scotia do it for sure.
