Ontario Blue Cross is a registered trademark in Health Insurance.

The Blue Cross plan was backed by the Ontario government as a vehicle to pay for health care costs in hospitals in the province.

[4] From 1985 to 1995, Blue Cross repositioned itself due to political changes causing large losses.

This led the OHA to sell its Blue Cross assets to Liberty Mutual Insurance in March 1995.

[6] In May 1999, the Canassurance Hospital Service Association purchased Ontario Blue Cross.
