Canada Post has presented its latest contract offer to the Canadian Union of Postal Workers in a bid to reach a new deal without a labour disruption.
The new proposal includes annual wage increases amounting to 11.5 percent over four years.
It also protects the defined benefit pension for current employees, as well as their job security and health benefits.
The union announced earlier this week that its members voted overwhelmingly to support a strike if a deal could not be reached at the bargaining table.
It said preliminary results showed 95.8 percent of urban workers and 95.5 percent of rural workers voted to back the strike mandate.
A cooling-off period in the contract talks ends on Saturday.
