Canadian politician offices typically have constituent services. They usually have access to MP-only phone numbers to sort out regular snafus (often immigration related). But if you’ve been caught in a systematic issue that the government created, and your MP belongs to that party, your MP is unlikely to take any action whatsoever.

You can also email the prime minister and sometimes they’ll forward it to the Minister responsible and then they have to reply. Just make sure to phrase it as a non-systemic issue when it was a systemic issue they created ;)
