In addition, Gregory handles general civil litigation disputes. I work to find the best possible solution and the best, most practical way to achieve it... even if it’s not litigation in the courtroom.

Value to Clients

My team and I bring a collaborative approach to client service. While we frame legal issues and anticipate how claims and disputes will play out, our clients are the experts in their fields. We work together with our clients to come up with the right strategy.

Client Stories

Serving clients proactively

• A professional regulator was sued by a member of the organization who alleged bad faith investigation, negligence and abuse of process. Gregory investigated the claims and took the client through a risk management exercise. I sat down with my client the regulatory body and looked at what happened, where its processes could be improved and whether the claim had merit. We filed a motion to dismiss the claim and then assisted the group to improve its processes to avoid similar issues in the future.

Protecting our clients’ assets

• Another professional regulator was having trouble enforcing its legislation prohibiting non-members from using reserved professional titles. Companies were using the reserved titles in their business names and ignoring the regulator’s requests to change their names. Gregory filed court applications against the companies and the Registrar of Corporations and obtained court orders compelling the Registrar to change the corporate names when the companies wouldn’t.
