Five stars all around
Switched to Williams & Nicholson Insurance on a friend's recommendation and I'm so glad I did. My auto insurance premium dropped and I actually have better coverage now.

From the first call to signing the policy, everything was handled professionally. Williams & Nicholson Insurance really knows the insurance market in Ontario.

Does the job
Williams & Nicholson Insurance helped me find auto insurance after I moved to Cornwall. Decent rates and good coverage. Not the most high-tech office but they get results.

Helpful staff
The staff at Williams & Nicholson Insurance were helpful when I needed to add a new driver to my auto policy. They found a way to keep the premium increase minimal.

Poor communication
My biggest issue with Williams & Nicholson Insurance was the lack of communication. I had to call multiple times to get updates on my home insurance policy. Frustrating.

Excellent service
After a car accident, Williams & Nicholson Insurance guided me through the entire claims process. I felt supported every step of the way. Cannot recommend them enough.
