OTTAWA — A senior federal cabinet minister says Canadian government computer servers have been cyberattacked.
Treasury Board President Tony Clement tweets that until full service is restored, the public should use 1-800-OCanada.
The message comes after some had difficulty accessing certain government websites.
Denial-of-service attacks are a common means of shutting down a web server.
Confirmed today that Govt of Canada GC servers have been cyberattacked. Until full service is restored please use 1-800-OCanada.

The Anonymous online collective posted a video on YouTube claiming responsibility for the attack as a protest against the recent passage of the federal anti-terrorism bill.
There was no immediate confirmation of the claim.
