Insurance policies, and insurance limits, must be disclosed in the discovery process in British Columbia.
Effective July 1, 2007. British Columbia has amended the Rules of Court to require parties to disclose the existence and contents of any insurance policy which provides indemnity for a judgement, or which provides direct payment of a judgement. However, the existence of any insurance policy cannot be disclosed to the Court hearing the case.
I have attached a link which contains the amendments to the Rules here.
