Prime Minister Justin Trudeau is giving indications that his patience is running out with Canada Post and the ongoing labour disruptions.
The P-M signalled that his government might soon act to end the dispute if the Crown corporation and the Canadian Union of Postal Workers can't bridge their differences.
Trudeau's comments come as CUP-W members expanded their rotating walkouts to hit dozens of locations across the country, including in Quebec, Ontario, British Columbia and Nova Scotia.
The labour action impacted Niagara this week.
