Since you were married in the Philippines your marriage still stand. Even if you get married in hongkong your papers will still be processed in Manila Visa Office, and they will need PSA documents which will show you are legally married to the new guy, but unfortunately you cannot since your old marriage still stands. The solution is you have to hire a lawyer in the Philippines and apply for a Recognition of Foreign Divorce, which like the name states will legally recognize your divorce in Canada, the caveat is that you must be a Canadian Citizen already when you were divorced. This is a lengthy process, you will go through hearings and such, then after the court says it is recognized then it will direct PSA to put annex to your previous marriage certificate that a divorce was recognized then that is the time you can get married then sponsor your new husband. It took me 3 years for the entire process.
