Many union bosses distanced themselves when a union representative in Toronto made a YouTube video comparing Prime Minister Stephen Harper to Adolf Hitler in a protest against proposed legislation that would force unions to disclose detailed financial information.
But it appeared the prairie-based Grain and General Services Union was on side when it promptly reposted the controversial video on its website.
Humberto DaSilva tells Canadians in the video that if they don't protest Bill C-377 they should "shut up and wait for your boxcar."
Hugh Wagner, the GSU general secretary, said the video was posted without his knowledge when he was asked if the union supports the clip.
"While GSU profoundly disagrees with Bill C-377 we do not agree with nor endorse Mr. DaSilva's inappropriate characterization of the prime minister," he said.
He said he has ordered the video to be removed from the grain union's website.
