More than two years after Quebec officials barred a security contracting business from provincial contracting, federal procurement officers have imposed their own five-year ban — but not before a related company landed a contract. 

The ban on Neptune Security Services Inc., a former federal contractor based in Mississauga, Ont., follows Quebec’s March 2023 decision, which was based on a probe that uncovered unauthorized subcontracting and alleged efforts to mask who controlled the company.
