Turnbull Associates, owned and operated by John Turnbull was established in 1992, while John was working as a Corporate Private Investigator. Looking to future opportunities, John obtained accreditation to do “Asset Appraisals” through the “Canadian Personal Property Appraisers Group” and remains a member in good standing.

Retiring from the world of private investigation, a network of trusted professionals was developed to assist companies and individuals with numerous business issues.
