I often get FedEx shipments from DigiKey originating from Winnipeg, MB.
Perhaps bulk routed through there, but definitely not (physically) originating there.
Indeed.
It clears customs in Winnipeg but everything from Digikey actually originates from their warehouse(s) in Thief River Falls, Minnesota.
Many things that clear using bulk, third-party customs clearing systems will show as originating from somewhere here in Canada, because that's where the Canadian side of the courier picks it up from, after the packages have been sent into the country in a larger load and customs cleared.
I ordered some headers and a Super Coil from Summit Racing last week (came from an Ohio warehouse) which didn't show up in FedEx's tracking until it was picked up as "originating" in Woodbridge, Ontario. This is very common with larger volume sellers that have their own customs-clearing arrangements.
(As an aside, FedEx did a nice job once in Canada, they weren't supposed to show up until yesterday but they showed up on Saturday, the driver said they've got a backlog so were offering extra Saturday shifts to do bonus deliveries...
Worked out great, was able to drop them off at the local ceramic coating shop yesterday.)
