Canada’s mail system ground to a halt after 55,000 members of the Canadian Union of Postal Workers walked out on September 25, hours after Ottawa ordered sweeping changes at Canada Post to stem mounting losses. The strike freezes letter and parcel movements just as retailers ramp up for holiday shipping, setting off a scramble across private networks that will spill into trucking lanes on both sides of the border.
Canada Post confirmed it is not processing or delivering mail or parcels during the national strike and has suspended service guarantees; limited exceptions remain for socio‑economic cheques and live animals already in the network. The corporation warned that backlogs will linger even after operations restart. For carriers and shippers, that means weeks of catch‑up volume once a settlement is reached.
The walkout followed a federal directive to “begin transformation” at the crown corporation, including lifting the moratorium on door‑to‑door delivery and converting the remaining four million addresses to community mailboxes; shifting non‑urgent letter mail to ground to reduce costs; and modernizing the retail network. Ottawa says those moves could deliver hundreds of millions in annual savings and help address daily losses of roughly $10 million amid steep declines in letters and parcel market share.
Business groups responded quickly. The Ontario Chamber of Commerce urged an “immediate resolution,” warning that 80% of small businesses rely on Canada Post for deliveries, invoicing and payments. Nationally, chambers and industry associations pressed both sides to return to negotiations to avoid another peak‑season supply chain shock.
Private networks are already adjusting. eBay told sellers it has temporarily disabled USPS options to Canadian addresses in its shipping tool and is routing through alternate carriers. Shipping platform Shippo likewise said it disabled USPS service levels to Canada in its app and API while the disruption persists. Those moves redirect more parcels into integrators and regional couriers — and, by extension, into the middle‑mile and long‑haul trucking capacity that feeds their hubs.
For trucking operators, the near‑term picture is a reshuffle of parcel flows rather than a drop in demand. Expect:
– Heavier B2C and returns volume funneled to private carriers’ terminals in the Greater Toronto and Greater Vancouver corridors, requiring extra linehaul and trailer capacity to protect service levels.
– Cross‑border freight mix shifts as U.S. merchants divert Canadian deliveries away from postal channels; LTL carriers and cross‑dock operators near Detroit–Windsor, Buffalo–Fort Erie and Blaine–Surrey should plan for elevated small‑parcel injections and tight appointment windows.
– Flyer and unaddressed‑mail pauses pushing more retailers toward digital promos and direct courier drops, which can increase same‑day/next‑day runs in urban markets and pull in additional sprinter and straight‑truck capacity for overflow.
The government’s restructuring blueprint also has medium‑term implications for ground networks. Moving non‑urgent letters from air to road and phasing out door‑to‑door will concentrate activity in depot‑to‑community‑box routes, creating steadier regional linehaul and P&D patterns — but only after the current labour dispute ends and new operating plans are implemented.
As of September 26–28, federal mediators were still encouraging talks. The Canadian Chamber of Commerce called for good‑faith negotiations, and the union signaled Canada Post would table fuller proposals “next week.” Until a deal materializes, parcel capacity tightness — not a lack of freight — is the trucking industry’s central risk heading into October.
What carriers can do now: prioritize contracted customers to manage injections; stage extra trailers at high‑throughput parcel hubs; pre‑clear cross‑border paperwork to avoid yard dwell; and stay synchronized with retail DCs on cut‑offs and exceptions so downstream drivers aren’t stranded on missed pulls.
