I send everything to the CRA via courier with proof of delivery. They still lose documents, and conveniently the person who signs for it signs under the name "revenue canada" or "CRA" rather than using a real name to establish a paper trail.
The MP can help. Going to the minister of national revenue asking why his department misplaced my papers 3x, and here's the Canada Post proof of deliveries, will get you a resolution quite quickly.
