You have my sympathy. I think this is also the longest wait I have heard of. My own application took 2.5 years and I don't even know why because everybody else was getting them in around 1 year in my area at that time. Frankly, I suspect they lost my application behind a desk and found it again during spring cleaning or something like that.
Have you considered trying to withdraw your application and applying again? Have you talked to a lawyer about this option? I suppose they may not accept a withdrawal at this point but if they have lost your file and wont admit it, that would be a way out for them. Have you ordered your GMCS notes to see what is going on with your case if anything? Have you taken your story to the media?
I suppose you could renew your passport if you want to travel. Do you still have a valid PR card? Did you get your PR card renewed at some point since the RQ?
