Our Story

The names ‘Warner’ and ‘Insurance’ have been associated together on the Cornwall landscape for over 60 years. Doug Warner, John’s father, began selling life insurance in 1946. John started operating a general insurance brokerage in 1990.

With that brokerage, John has become a Chartered Insurance Professional with the Insurance Institute of Canada. Bill Griese is one of the most knowledgeable insurance people in Eastern Ontario, and is also a Chartered Insurance Professional. Judy Lamarche, Kerry Van Allen, Theresa Wattie, Sebastian Warner, and John Symington are all licenced brokers who work with John and Bill, offering quality in all aspects of their service to the public.

In 1999, Warner Insurance opened an office in Vankleek Hill, which is currently staffed by Linda Vernier, and Sebastian Warner. Linda and Sebastian are licenced brokers, pleased to offer their professional services to the Vankleek Hill and Hawkesbury region of Eastern Ontario.

At Warner Insurance, we believe our service is second to none. We are a small service orientated office that takes the necessary time to deal with our client needs. We are committed to the protection of our communities.
