Can a ripped Canadian Plastic Bill with 60% portion of the bill remaining containing both serial #s still get full value?
You can read about the procedure for requesting reimbursement for mutilated Canadian currency at the article Contaminated and Mutilated Bank Notes. However, they do not seem to give any specifics about how they determine whether a bank note is eligible for reimbursement or not, so it may be a case-by-case decision. But it seems like you might as well try it - you just have to fill out a brief form and mail it in with the banknote. If the Bank of Canada won't reimburse it, presumably nobody else would either.
