Both sides say their negotiators remain at the table as a Senate vote on legislation that would force an end to rotating walkouts at Canada Post inches closer.
Canada Post says it's delivering packages this weekend, but at much lower volumes than normal at this time of year.
A spokesman for the Crown corporation says work restrictions imposed by the Canadian Union of Postal Workers, including a ban on overtime, mean about 30,000 parcels will be delivered to Canadians over the weekend.
Jon Hamilton says that number is normally in the range of 500,000 packages in late November.
The Senate is set to resume debate tomorrow afternoon (2 p.m. ET) on back-to-work legislation that was introduced by the Trudeau Liberals last week and passed in the House of Commons.
A Senate official says a final vote on the bill is expected tomorrow, possibly by early evening with royal assent soon afterwards, barring any proposed amendments that, if passed, could see the legislation returned to the Commons.
In Toronto, striking workers took to the picket lines at the York Distribution Centre in Scarborough, Sunday afternoon.
"I'm hearing that there was some movement after the legislation was introduced on Friday," president of Scarborough CUPW Local 602 Mike Duquette told NEWSTALK1010. "I'm hopeful we can still get a resolution to this."
"A negotiated agreement is much better than an arbitrated agreement because I've seen - in my history - arbitrators render a decision that both sides are unhappy with, and that can be problematic for both sides."
Duquette says he thinks Bill C-89 is unconstitutional, similar to legislation introduced by then-Prime Minister Stephen Harper in 2011 that was overturned, as it calls for final offer selection. This means only the employer or the union offer can be accepted, which he says doesn't allow the sides to come up with a fair compromise.
"If there's movement at the table, I think it would be counterproductive to proceed [with Bill C-89]," he added.
