Call 1-800-910-4222 before authorizing any repairs outside the province. Find out if your car can be repaired where you are or whether it will need to be brought back to British Columbia.
Some repair shops outside B.C. may not accept payment directly from ICBC. You might have to pay for the repairs first and apply for reimbursement when you get back home.
Keep a copy of the repair shop's bill and supporting invoices for parts and materials. You will need these for reimbursement.
