Ever since he became Con leader, after a leadership race that reeked of corruption, Andrew Scheer has been blowing a giant dog whistle the size of a house.
Seeking to whip up hatred against Muslims, refugees, non-white immigrants for crass political purposes.
And thanks to our grubby Con media, he has somehow managed to avoid being tagged as a bigot.
But not any longer.
Justin Trudeau has had to deal with all kinds of crazed hecklers as he travels across the country.
There's one being removed from a town hall in Quebec City last January, with a Canadian flag defaced by a swastika.
But the way he dealt with an aggressive heckler from the far-right group Storm Alliance, while surrounded by other members of that group, had to be one of his most magnificent moments.
If only for the message he sent out at a time when fascists are on the move all over the world:
"Racism has no place in Canada."
