With a few hours left until the strike deadline, Canada Post and the union representing its workers have yet to reach a deal.

The two parties met Thursday night, which, according to Canada Post, lasted less than an hour.

The Crown corporation added that the Canadian Union of Postal Workers (CUPW) raised “only a small number of outstanding issues in an informal manner.”

“It was unfortunately not enough to demonstrate meaningful progress. We asked them to come back, with urgency, with a response to the Global Offers we presented to the union on May 21,” Canada Post said.

In a bulletin posted late Wednesday, the CUPW said it is still reviewing proposals tabled by the Crown corporation earlier in the day.

But it identified a number of areas where the offers disappoint, namely on wages and cost-of-living adjustments.

Canada Post’s offers amount to a little more than 13 per cent in wage increases over four years, where the union was looking for closer to 19 per cent to catch up after years of rampant inflation.

The union also raised concerns about Canada Post’s pitch to include more part-time staff and introduce “dynamic routing” -- a model that could see mail delivery routes change on a daily basis to adjust to varying conditions -- without established rules governing the system.

CUPW also argued that the six extra personal days on offer are “window dressing” and already allotted in the Canada Labour Code.

The union also took issue with a pitch to remove workers’ “five-minute wash-up time.”

Without an agreement in place by the end of Thursday, CUPW members are set to go on strike shortly after midnight.

Canada Post rejected CUPW’s call for a two-week “truce” that would have given the union time to review the new offers in detail.

If postal workers do walk off the job, it would be the second time in less than six months.

Jobs Minister Patty Hajdu is overseeing the file jointly with John Zerucelli, secretary of state for labour, Hajdu’s spokesman John Fragos said Thursday.

Hajdu last spoke with the two parties on May 16, when they discussed a newly released report -- commissioned by the federal government and written by arbitrator William Kaplan -- outlining the “existential crisis” facing the Crown corporation along with recommendations, Fragos said.

Federal mediators are in touch with both sides daily, he said.
