I wish I could give you a concrete solution to this problem. I think this is something that chief electoral officers are discussing amongst ourselves. This is a new facet and regime that we're seeing with the advent of the Internet and these large social media companies that, as you correctly articulated, can direct messaging to a certain segment of society.
At this particular time as an electoral administrator, I don't have a clear-cut solution for you. I think it is something that legislators, experts in the field of social media, and electoral administrators need to work on to find an effective solution. I do believe Canadians would expect that of us.
