As a former property manager, who worked with many expats, or non resident taxpayers, we did it, but prefered not to. Some folks are very honest, and filed their paper work on time including paying the tax bill. But there were a few who did not, and Revenue Canada chased after the agent for the owner for the money. So we occassionally were left holding the bag (or having to pay the bill).
There is no course on Non Resident Tax and the rules in any property management course. I learned about NR's in 1990 with a shareholder in an murb syndication for an multi family property. And the client was an international banker, who should have knowen the rules and did not.. He had to file taxes for 6 previous years. He payed a pretty heavy fine for not filing.
Short answer, don't be surprised if your property manager is not aware, and if they are, be prepared for a surcharge to handle the taxes on your behalf.
