You may have found me wrong, I didn't want to offend you in any term.
I've just read first couple of lines of the link. Even if it's mandatory requirement, it's bestowed upon FILIPINO EMIGRANTS, not FILIPINO IMMIGRANTS to CANADA. So, it may be a rule of Philippines, cannot be for Canada. If it were a rule for anyone immigrating to Canada, we would all know this by now. When you first asked, you kind of generalized all immigrants as none may not have any clue re: this. Therefore, only a FILIPINO who immigrated from Phillippines can answer to your query.
