Historically, the Russian trolls have been very much invested in supporting the far right in different countries. It's not only in Canada, but also in the U.S. and in many places in Europe. The reason is definitely to create tension.
There is a term called “agitainment”, which means making people really agitated, but at the same time entertained. That is done using, for example, funny memes and funny messages, but they are very much militant, aggressive and often racist.
You can see a pattern. This pattern shows that the Russian trolls usually align themselves with extremes and sometimes even with the far left.
That's the strategy in general. Often the targets will be the minority groups, especially refugees and immigrants in different countries. The focus sometimes will be on the Netherlands or in the U.S.A., but that will be the main issue.
I hope I answered your question. Did you want me to focus on today?
