Public hearings into the provincial government's pension reform plan Bill 3 begin this morning in Quebec City.
They are taking place amidst heated tensions between the Couillard government and the public sector unions.
The public hearings will hear from the cities of Montreal and Quebec this morning.
The province's two big unions, the CSN and FTQ, will testify in the afternoon.
But they'll be doing so in an atmosphere that's highly charged followed what's been described as the union's assault on City Hall on Monday.
Quebec premier Philippe Couillard joined those denouncing the disruptions.
"Anger or disagreement can never be justification for behaviour of that kind," he said.
The unions have also taken out full page ads in daily newspapers and released a YouTube ad targetting Quebec City mayor Regis Labeaume.
