I am planning to retire in BC and would like to sell real estate part-time.

Aways get your information from the institution that the information concerns. Information about rules laws of another country, write their Consulate/Embassy and request their printed documentation. Telephone calls are always a bad idea. Documentation is valid in court.

The same holds true here in America or any country. If you want tax information, write IRS. You want immigration info, it is The US State Dept And INS, Always request their Documentation for the subject of your interest.

NEVER listen to the public at large. Never take the spoken word
as being valid. People change what they say. GET DOCUMENTATION from the organization.
