The Gowlings Energy Team is among the best in Toronto.’

Working with them provides me with the legal and regulatory expertise I need, but also allows me to challenge them on certain aspects that I feel could be done differently. These discussions are always handled respectfully and competently.

On a personal level all of these individuals are a pleasure to work with. Technically and legally talented but approachable, friendly and reasonable. I very much enjoy my interactions with Gowlings.

Gowling stands out for its senior energy regulatory expertise. Ian Mondrow is my go-to counsel for work on strategic regulatory matters, he has a great depth of experience and cross-jurisdictional knowledge that I have not found in in this practice area elsewhere.

Ian Mondrow is very practical and customer-focused and is very personable and easy to deal with.

The practice is respected by the regulator, so was able to influence outcomes. Also, they were very well versed in the issues we were involved in.

The individuals were engaged and exerted their influence to get a good outcome. They arranged phone calls with other parties to negotiate a favorable outcome.
