The new proposals include annual wage increases of nine per cent in the first year of the agreement, and four per cent in the second year, followed by hikes of three per cent in years three and four. That’s up from the roughly 13 per cent over four years included in Canada Post’s most recent offers from late May.

In an interview with Reuters, Mike Rousseau blamed the impasse on a gap between the airline's offer and its union's demands.

The union's counter-offer to Canada Post requests a 20.3 per cent wage increase over four years, much higher than the Crown corporation's "final offer" of 13 per cent.
