Can I use professional liability insurance coverage obtained in another province to meet BC requirements?

This depends on whether the professional liability coverage you have covers activities in BC. If the professional liability insurance coverage obtained in another province covers your activities in BC, then you may use it to meet the CPBC registration requirements. 

If the coverage you have obtained does not cover your activities in BC, then you will be required to purchase new or additional professional liability insurance to meet the CPBC registration requirements.
