People in some parts of Winnipeg are not getting their mail regularly, which Canada Post is blaming on the extremely cold weather and a staffing shortage.

Some areas in the city have been getting what Canada Post calls "alternating delivery," while some streets haven't received any mail in days.

Delivery to Bob Burd's home in the West End has been sporadic over the last few weeks. For a week, the mail didn't come at all.

"We had bills that come in, and they were late. That's good, too; I don't mind that," he laughed.

Given the extremely cold temperatures and high snowfall amounts in Winnipeg in recent weeks, Burd said he doesn't blame mail carriers for the delays.

"It's been slow in some cases because of the snow. I realize that. You see these guys trucking out there, you know, trying to get through," he said.

"And the cold. Oh, the cold. You know, they're bundled up and that's all you see, is their eyes."

Canada Post officials told CBC News that extreme weather conditions and a staffing shortage have led to some delays in mail delivery.

Unsafe delivery conditions, such as walkways that have snow piled up on them, can also result in mail not getting to some homes, officials added.

Staffing an issue, says union

The Canadian Union of Postal Workers says while weather has been an issue, the real problem is not having enough staff.

Darren Steinhoff, the health and safety officer with CUPW's Winnipeg local, said he knows of at least 14 city routes that have not been covered for days at a time.

"We've seen a number of walks in the different installations that have not gone out for three, up to four days as a result of the employer not making sure that there's adequate staff, you know, in order to backfill people that are off on their vacation leave or off on a leave of absence due to illness or whatever," he said.

Steinhoff said carriers are trying to pick up the slack, but there is only so much they can do.

"It's very important to us that we get the mail out to people, and so people are taking on the extra responsibility," he said.

"But you know, 10 [to] 12 hours and with this type of weather, you can only withstand that for so long before members go, 'I've had enough, I can't do any more now.'"

Canada Post has not said when service will return to normal, but officials say some managers are helping with delivery to speed things along.
