New residents of B.C. are eligible for coverage after completing a waiting period that normally consists of the balance of the month of arrival plus two months.
You should apply for coverage immediately after arriving in B.C., to allow time for your application to be processed.
The Ministry of Health and Long-term Care website also states that if you are an insured resident moving to another province, you should apply for health coverage in your new province or territory as soon as possible.
You can only obtain health coverage from one province or territory at any time.
Your Ontario health coverage will remain in effect until the last day of the second full month after you establish residence in your new location.
All the best in your new province!
I hope this information is helpful. Please let us know if you have further questions and if there is any follow up to your question/situation.
