Collision repair shops in Manitoba fear they are headed for a crash of their own regarding negotiated rates paid by Manitoba Public Insurance. The Manitoba Motor Dealers Association and an organization that represents independent body shops in the province say the public insurer has unilaterally ended negotiations on a renewal of its two-year rate agreement, a process that has been in place for 50 years. Collision repair shops, through the MMDA and the Automotive Trades Association, have asked for a significant hike in hourly labour rates and rates paid for specific procedures that MPI says would cost the public insurer $100 million per year and would cause a significant rate hike to Manitoba ratepayers.
