1988:
Corporate Investigation Services (CIS) begins its life as London Protection & Investigations. Founded at 75 Main Street in Lambeth, Ontario by partners Guy Parent and Phil Thompson, the company is formed in response to the closure of their former employer, Can Am Protection. In December 1988, Fleck Manufacturing contracts CIS to closure their plant so they can relocate operations to Mexico.
1990:
CIS pursues investigation and strike response opportunities throughout Southern Ontario; and opens an office in Windsor, Ontario to serve the automobile industries need for investigations of WSIB fraud and abuse.
1991:
CIS establishes an office in Vancouver, B.C. in response to a prolonged strike in Richmond. CIS also forms a Retail Investigation Division in London, Ontario with investigators dedicated to apprehending shoplifters, as well as a covert CCTV installation division.
1993:
After five years of partnership and a steady increase in business, Parent and Thompson mutually agree to discontinue their partnership. Guy Parent, now sole owner and president of CIS, retains the Windsor branch office and relocates the Lambeth main office to 2410 Main Street.
1994-1995:
Thanks to a two-year growth spurt, CIS moves from renting facilities at 2410 Main Street to purchasing 2417 Main Street. At this time, Corporate Inquiry Systems is born in response to our customers needs: we would help HR Managers evaluate and qualify their employees, and thus reduce the need for investigations.

Outgrowing the main office at 2417 Main Street, CIS also purchases 2410 Main Street as its second location. The additional office space accommodates the Investigation and Labour Unrest Services, with room for growth.
