This is a question to be asking, yes.
One of the things that is currently occurring in the U.S. election cycle is the integration of different forms of data from different sources. The availability of personal data in the U.S. is far more extensive than it is here. The integration of marketing data, geo-demographic data, as well as the tracking of online behaviour, is becoming very extensive. It has allowed American political parties in a far more sophisticated way than before to segment the electorate, to divide up the electorate, and to target supporters and potential supporters according to increasingly precise demographic characteristics.
On the face of it, there's nothing in principle wrong with that, but the United States doesn't have any privacy protection rules anywhere near as strong as those in Canada. Yet in Canada, we have seen that political parties here have learned from time to time from their American counterparts.
I would raise the question about whether or not what has been going on in the U.S. might be seen here in the future and whether those kinds of practices are going to raise the concerns of Canadian citizens to the extent that it will be a far more high-profile issue than it is at the moment.
