If Facebook offered a political party the opportunity to advertise on Facebook and, a week before the election, it provided a list of 620,000 Canadians who had watched the advertisement about its leader, it would not mean that the vote of those Canadians would be assured or that they intended to vote. On the other hand, if, coincidentally, a second advertisement from the party was broadcast encouraging people to vote according to the values of the party, and it appeared four or five times a day on their Facebook pages in the week before the election, could it have an effect, especially if those people had said that they had seen the previous advertising? That would be more than profiling. That would be inappropriate.
