Individual Canadian immigrants are exempt from the requirements to file a T1135 information return for the year in which they first become Residents of Canada. While new Canadian residents do not have to file the T1135 form, they still have to report all of their worldwide income including any foreign source pensions. It’s also important to realize that residence for Canadian income tax purposes is not the same as landed immigrant status. Our top Canadian tax lawyers can advise if you have become a Canadian tax resident.

1. I own a property in my home country. Is there anything I need to do before/after I land in Canada?
There are different tax implications in this case.
a) Establish a new cost base for your properties before landing
Immediately before you become a resident of Canada, you will be deemed to have disposed of your home and have reacquired it at the fair market value. As such, you will pay tax in Canada upon the actual disposition of your house only on the gain which you earned after you became a resident of Canada. The rule applies to all the properties in the country you reside before moving; as well as the properties you already own in Canada. An evaluation of the value of the properties will be necessary to determine the fair market value (i.e. new cost base) at the time you became resident in Canada.
Example
Thomas Chan bought a home in Hong Kong before he immigrated to Canada:
The actual price he paid in 2010: $2,000,000
Thomas immigrated to Canada in 2017 and the "fair market value" of his property when moving: $5,000,000
Thomas had his realtor in Hong Kong sold the property in 2019 for: $9,000,000
Under the Canadian income tax law, the "Capital Gain" derived from the sale is: = ($9,000,000 - $5,000,000) = $4,000,000
Thomas, as a Canadian resident, is now required to report the above-mentioned capital gain $4,000,000 in his 2019 Canadian tax return.
