As the above poster said, you will likely get better responses on the various Canadian centered fora. However, I couldn't help but chime in.
A brief internet search revealed numerous firms in Canada dedicated to helping Canadians living abroad which appear fully able to manage investments while their clients are abroad. Moreover, it's common sense that with any type of electronic account, the account should be manageable by the client from anywhere.
Accordingly, I am inclined to distrust and disbelieve what this financial advisor has told you. At the very least, you should be able to move this money to another advisor or better still to a brokerage account within which you could buy Vanguard ETFs.
See what the posters on the various forums linked to by the above poster say.
My only other advice is to contact the Foundation for the Advancement of Investor Rights at the link below (there is a "contact us" tab at the top of the page). They may be able to help. http://faircanada.ca/
