Russia is advising citizens to avoid travel to Canada, citing what it calls numerous cases of discrimination against Russians, including physical violence, its foreign ministry said on Saturday.
Canada is one of the most vocal backers of Ukraine in the war against Moscow's forces and has imposed sanctions on hundreds of Russian officials and companies as well as wide-scale trade bans.
Shortly after the war started last year, Canada advised citizens to avoid all travel to Russia.
Russia last week imposed sanctions on 333 Canadian officials and public figures, including prominent Olympians, in what it said was a tit-for-tat response to Canadian restrictions on Moscow and support for Ukraine.
