Canada Post workers in Niagara Falls are off the job again.
While negotiations continue, the Canadian Union of Postal Workers began strikes this morning in Niagara Falls, Stratford, Owen Sound and Windsor.
Workers are off the job in other parts of the country, and a number of distribution centres in the GTA are also shut down.
Since October 22nd, CUPW's rotating strikes have shut down operations in more than 200 communities across the country.
Canada Post says they are working hard to maintain service to Canadians, but as Toronto is a key processing hub for mail and parcels, the union's job action is having a significant impact on service.
