WestJet says no credit card or banking information was disclosed in the privacy breach, but the Office of the Information and Privacy Commissioner of Alberta and the federal privacy commissioner have been informed of the incident. 

The company also said it has taken "immediate steps to secure affected systems."

WestJet didn't offer any detail on what kind of information was in the profile data or exactly how many rewards members may be affected by the breach.
