This is the moment a furious heckler refuses to shake hands with Justin Trudeau and calls the shocked Canadian Prime Minister a 'piece of s**t' for 'f**king up the country' over carbon taxes and the housing crisis.

The video, which has now gone viral, shows a confident Trudeau waving at supporters who had lined up to meet him as he marches up to greet them with his security guards standing just yards away.

The 51-year-old shakes someone's hand and waves at a child in a stroller before attempting to shake the hand of another crowd member who says: 'I'm not shaking your hand bro, you're a f***ing piece of s***.'
