At Precept Canada, we pride ourselves at being a dedicated group of specialized investigators. We are committed to providing quality investigation services to individuals, small business, major corporations as well as the insurance and legal industry across the country.

I have found Precept prompt, efficient, knowledgeable and thorough and I would not consider proceeding without their services when an investigation is required. The investigation is always proactive and interactive. Their rates are acceptable and their product reliable.

Mike Tweedie

Toronto Area Barrister

Our previous Investigative service provider went out of business a week before the onset of a significant project, leaving us with a great deal of prep and no investigators. On short notice Andy and Shannon put together a solution that worked out in the end and exceeded our expectations.
