Client Testimonials

“Having worked with Bruce for a number of years now he helped our company through a large restructuring that involved a number of difficult employee terminations. Bruce’s main strength was his ability to map out the process and provide a great strategy for managing ex-employees and their legal counsel in a professional and diplomatic manner, all the while controlling costs. He’s been a great help to our company.”

“Even for a seasoned business person, the nuances of the Canadian legal systems are extremely frustrating. You can throw out any concept of right and wrong when involved in a lawsuit. Although depth of knowledge of the law and how to maneuver through the legal system is extremely important what is equally important is the competency required to chart a winning course. In our case, a financial real estate development lawsuit, Bruce simply outmaneuvered all of our opponents. Furthermore his explanation of the tactical strategy was easy to understand and that’s important because it allowed me to trust him. The bottom line with Bruce and his team is that they’re always on your side.”
