I very much appreciate the question. I'll walk through part of it and then ask Ms. Acton to supplement.
You are correct in that creeping in of partisanship could be fairly subtle; it could be very much in the eyes of the beholder. I think, as a practical matter, a Canadian would likely search partisan advertising or something like that. The Google search engine would likely direct them to the appropriate place in both French and English. From there, they would submit their complaint.
Kelly, could you quickly review the process associated with that if there were to be a complaint?
