I'm not Canadian and I don't know the details of the situation, so excuse me if I'm wrong on this, but I think MP pay is a complex issue. It's easy to say "they get paid way more than the average person, of course they don't need a pay rise" but I think it's important to find a balance between that and paying enough that becoming an MP is an appealing option for intelligent, driven people. If they have a choice between an median salary as an MP and 15x the pay in the private sector, the most brilliant people are going to be drawn towards the private sector purely for financial reasons.

It's also important that they're given enough financial security that there's no risk of their finances being used as leverage against them. Some politicians will always just be corrupt and open to bribery or "lobbying", of course, but you don't want politicians that don't have their own money from other sources being put in compromised positions because of their finances. And you don't want politicians looking for other sources of income rather than focusing on their primary job.

Like I said, I don't know the details. Maybe Canada has already found a good balance - where it's already appealing to the best and brightest, and where their no risk of financial issues for MPs - and MP pay rises would be unnecessary. I just thought it was worth mentioning the fact that there can be some nuance to the situation!
