"Our view is that the brand isn't damaged," said Chief Executive Officer Michael Roach, 61. "We may see one-offs here and there, but I don't see anything that will last. We're prepared to talk to our clients about what we're learning here. We've not been banned from anything. We're not barred."

CGI, Canada's largest technology company, has bids in for about $1.3 billion in potential U.S. government business, Roach said yesterday in an interview at the firm's Montreal headquarters. Roach said he's also seeking contracts with states and corporate clients.

Roach's challenge is separating CGI from the fallout that followed Obamacare's Oct. 1 debut, as delays and error messages foiled applicants on the insurance exchange serving 36 of the 50 U.S. states. After years of providing services as basic as running the Medicare website and processing 25 percent of all U.S. passports, CGI found itself thrust into partisan sniping over the Patient Protection and Affordable Care Act of 2010.
