It depends on what kind of public they're targeting.
For younger people, that would be Telegram. For older people, maybe, or people who are not very confident with Telegram, there's Facebook. You can see so many bots on Facebook spreading Russian propaganda, and you can tell that those are not real people because they don't post anything else.
There are also Canadian Canadians, right, or immigrants in Canada from other countries. That would be other different media or also experts and professors in universities in Canada who spread Russian propaganda and visit Russia on obviously Kremlin-sponsored trips and then tell how great everything is in Russia and on occupied territories. Then they tour Canada and spread this information among Canadians.
There are definitely several strategies they use for different groups of people, but I can tell that those are working.
