After a two-week government-ordered voting period, the Canadian Union of Postal Workers (CUPW) shot down the dual proposals, which would have increased wages by 13.6 percent over four years and brought on more part-time workers.

Some 68.5 per cent of urban mail carriers who voted were against the deal, while their rural and suburban colleagues were 69.4 per cent against.

Canada Post's offer included a 13 per cent wage hike spread over four years, as well as a $1,000 signing bonus.
