Considering that a lot of Ukrainians in Canada were stripped of their civil rights and jobs, or even put in concentration camps during WW I, I'm pretty sure a lot of them would have had a thing or two to say about discrimination based on ethnicity.  Indeed, even modern Ukrainian cultural organizations secured an apology from the Harper government for the discriminatory treatment their forebears were subjected to during WW I.  It wasn't just hard work that allowed Ukrainian immigrants to eventually prosper, but also what they didn't have in the old country  -- equality under the law.
