However, if no other reasonable solution can be reached, Mathieu is prepared to litigate in court to advance a client’s needs. Mathieu stays current with changes in the law by regularly attending legal education courses, Canadian Bar Association seminars, and being engaged with legal research centers which enables him to provide the very best possible service to his clients.
