Canadian law allows foreigners (non-residents of Canada) to buy, own, rent, and sell property in Canada without many limitations. This open-door policy is similar to the approach to foreign property ownership in the US, UK and Germany.
It is most common to rent property in Canada directly through a landlord or property management company, rather than through a real estate agency. You can expect most landlords to speak English as a first language, except in Quebec and New Brunswick where most will speak French as a first language.
You may chose to sell property in Canada privately or with the assistance of a real estate agent. Non-residents should file a Canadian income tax return for the year in which the sale occurs. Non-residents should expect to receive a refund on a portion of the taxes paid.
