In 1996, Greg joined Crown Counsel and worked as a Crown Prosecutor throughout the Lower Mainland and the Sea-to-Sky Corridor for seven years. In this role, he prosecuted all types of offenses, such as murder, impaired driving and various types of assault. In doing so, he conducted hundreds of trials in the Provincial and Supreme Court.
