Because of freedom of expression and freedom of speech, I think it's important to at least flag these efforts and to talk about what the Russian embassy is doing in the public domain. I've already written a piece that I hope will be published soon on The Conversation website.
We cannot ban what is going on but at least flag what is happening and debunk, fact-check these claims and at least warn Canadians not to be enticed or drawn to this type of propaganda. It's the only thing we can do, I believe.
