It does not apply with respect to the collection, use, and disclosure of personal information within those provinces. So the cross-border aspect of data protection still remains within the federal purview. So for example, the Privacy Commissioner in British Columbia has full authority to investigate complaints there and exercise all of his powers in relation to any privacy issues within the province of British Columbia. If it was a complaint about a collection of personal information from a B.C. resident, but it had taken place by an organization in another province, then that would go to the federal Privacy Commissioner and she would exercise her authority.
I should mention that there's very close cooperation between the privacy commissioners across the country. All four privacy commissioners in Ontario, Quebec, B.C., and Alberta, but particularly the three that have comprehensive privacy protection laws, collaborate very closely on an operational level with the federal Privacy Commissioner. She will tell you more about how that works. But that's one of the ways in which they ensure that there are no gaps between their respective jurisdictions.
