Possibly.
First, when I recommend that PIPEDA be applied to federal political parties, it is implicit that context would matter. PIPEDA has a number of principles, such as the right to access information and the right to be clear on the purposes for which information would be used by an entity subject to PIPEDA. The fact that we would be dealing with political parties that have legitimate interests, if not rights, to engage in political discussion with electors would be part of the context.
As we would eventually look at the application of PIPEDA to political parties, certainly there could be an examination of enforcement mechanisms, the amount of penalties and what would make sense for the various entities that are subject to it.
I would end with this. In British Columbia, which is the only jurisdiction in Canada where political parties are subject to privacy law, I believe that the enforcement mechanisms are the same for parties as for other entities subject to that law.
