OTTAWA -- Canada Post has asked its international partners to halt mail and parcel shipments to Canada as it reels under the weight of a 30-day delivery backlog resulting from a labour dispute with its employees.
The Crown corporation said Friday that its domestic customers are also backed up with packages waiting for delivery as rotating strikes that began Oct. 22 continue across the country.
"The backlogs are also extending to international mail and parcels entering the country," Canada Post spokesman Jon Hamilton said in an email.
"As a result, we have been forced to request that international posts, including the United States Postal Service, refrain from shipping items until we can clear the backlog."
Britain's Royal Mail, in a bulletin to its corporate customers, said it would hold any shipments bound for Canada within the last couple of days in its distribution centres "awaiting further updates."
"As a result of ongoing industrial action, we have now been requested to suspend the dispatching of international traffic destined for Canada, from today until further notice," it said.
"This applies not only to us, but all international postal operators," the Royal Mail added.
A similar bulletin was issued by Hongkong Post and online sales giant eBay said it also received a notification from China Post that it was halting deliveries.
Canada Post and the Canadian Union of Postal Workers have been in contract negotiations for nearly a year, with no success.
CUPW began rotating strikes across the country that have shut down postal operations in over 200 communities, hoping to pressure Canada Post into agreeing to contract demands, including better job security, reduced workloads and stronger health and safety measures.
The walkouts have resulted in backlogs at the agency's main sorting plants, particularly in Toronto where Hamilton said the number of mail-filled tractor trailers awaiting processing had reached 407 as of Friday. Dozens of trailers were also sitting idle in Montreal and Vancouver.
The Crown corporation issued new contract offers this week aimed at reaching agreements with its approximately 42,000 urban employees and 8,000 rural and suburban carriers.
CUPW said the latest proposals made positive steps, but not enough to put an end to walkouts, which rotated Friday through most of Manitoba, as well as communities in Ontario, B.C., Alberta and New Brunswick.
The offers were time sensitive, with Canada Post imposing a deadline of Saturday at one minute before midnight for acceptance.
CUPW national president Mike Palecek wouldn't say whether tentative deals could be reached by then, but said the union would not be held to an arbitrary deadline.
Palecek was also critical of Canada Post for halting shipments from outside Canada.
"There is no reason to halt international shipments," he said in a statement. "Let us solve our issues at the bargaining table."
The union said it wants concrete proposals for dealing with an escalating number of work injuries at Canada Post.
Hamilton said the corporation has proposed a way for the company and union to work together to identify ways to make the workplace safer, and offered to fast-track a review of workloads to reduce overburdening of carriers who have seen a rapid increase in the number of parcels they have to deliver while letter volumes have declined.
Prime Minister Justin Trudeau warned last week his government will act to end the rotating strikes if there is no significant progress in the negotiations. Trudeau did not specify what type of action might be taken, nor did he provide a timeline.
Earlier this week, eBay called on Trudeau to legislate an end to the dispute in time for Black Friday and Cyber Monday sales events tied to American Thanksgiving that begin Nov. 23.
