Do you have sufficient funds?
The Government of Canada does not provide financial support to new skilled worker immigrants.
You must show that you have enough money to support yourself and your family members after you arrive in Canada. The money must be available to support the costs of living for yourself and your family. The amount is an estimate of what you would require to support yourself and your family without employment or other income. You cannot borrow this money from another person.
The amount of money you need to support your family is determined by the size of your family. These amounts are updated every year. Check our website to make sure you have the most recent information.
We strongly recommend that you research the cost of living in the region of Canada where you intend to live. To make your establishment in Canada easier, bring as much money as possible with you to Canada.
