In Canada, federal political parties conveniently scoped their data operations outside of federal privacy legislation when it was written. Then, when provincial legislation threatened those parties' data collection operations, the federal parties subtly changed federal law in order to claim that federal political parties' data collection was exclusively under federal jurisdiction:
> The amended petition from the Liberal Party argues that the passage of C-47 “expressly confirmed Parliament's intent” that the collection and use of personal information by the federal parties “be governed exclusively by federal law.”

The question of whether that kind of jurisdictional excision can be performed is now before our courts.
