Airport security firm sues Canada for $420 million after failed contract bid

TORONTO - A multinational security firm that used to provide screening services at airports in British Columbia and the Yukon is suing the Canadian government for more than $420 million after being replaced by a rival bidder last year.

Universal Protection Service of Canada Corp., known as Allied Universal Canada, filed a statement of claim in Federal Court this week seeking damages for lost profits from the federal government and the Canadian Air Transport Security Authority.
