Are you going to Canada to work for the Summer? Read this.
All Working Holiday applicants must arrive at the Canadian port of entry with the full 2 years of insurance. Those arriving with insurance for a shorter period will receive a work permit for this period only.

To avail of your full permit, make sure you arrive with proof of 2 years of insurance. For more, see this:
