Very hard to say. Does your MP's office say anything more? Did you ask them for more assistance? Were you able to clarify whether criminal/police/securty checks are complete? Anything in the gcms notes that might indicate issues there?
The 'awaiting review' sounds a bit unlikely to me based on the other things you've said; criminality or security delay sounds more likely - but this is only a guess.
You could try a letter to Minister of Immigration with copies elsewhere (mp, opposition/NDP immigration critics, etc.)
I'm more skeptical of the writ of mandamus idea but would look at it this way: IF the problem is just bureaucratic (eg the officer has not picked up the file for review or its physically at bottom of a backlog pile), ircc MIGHT process quicker to just not have to deal with the legal aspect. IF there's an actual issue, may not speed anything up and just cost money, possibly a lot to follow it through. Caveat, not a lawyer and this is not advice - and it's not my money.
Good luck.
