Learn what to do when you are leaving the province - go to Leaving B.C. Note: If you leave B.C. you will continue to be billed for premiums, unless you notify MSP that you are moving away permanently and no longer require coverage.
Cancelling Your Coverage
If you will no longer be a resident of B.C., you must notify MSP of the date of your departure and your new address; otherwise, premium billing may continue. If possible, use one of MSP’s online Address Change Forms. (Note: failure to pay premiums does not constitute notification to cancel your coverage.)
