Canada Postal Strike Update 2025: Rotating Strikes & Delays

If you’ve noticed your mail arriving later than usual, you’re not alone. Canada Post has been locked in a labour dispute with the Canadian Union of Postal Workers (CUPW) since late 2024, and the rotating strikes that escalated in September 2025 are causing unpredictable service gaps.

Strike start date: November 15, 2024 ·
Strike suspension date: December 17, 2024 ·
Postal workers affected: ~55,000 (CUPW members) ·
Current action type: Rotating strikes (since September 2025) ·
Tentative agreements reached: December 2024 (not yet ratified)

Five key facts sum up the situation in a glance.

Is the Canada Post strike over yet?

The first nationwide strike by CUPW ran from November 15 to December 17, 2024, when it was suspended after a tentative agreement was announced (Wikipedia (community-edited encyclopedia)). However, that deal was never ratified by the membership. After months of stalled negotiations, CUPW escalated action again.

Has the strike been suspended?

• The 2024 full strike was suspended on December 17, 2024 (Wikipedia).
• A new national strike began September 25, 2025 in response to government-mandated reforms (Labor Notes (independent labor journalism)).
• That nationwide strike was suspended on October 10, 2025, replaced by rotating strikes (Wikipedia).
• Rotating strikes were suspended on November 21, 2025 after a new tentative agreement (Wikipedia).

What is the current CUPW action status?

• As of the latest reports, CUPW had suspended the rotating strikes on November 21, 2025, pending ratification (Wikipedia).
• Canada Post’s official page confirms ongoing disruptions due to the labour dispute (Canada Post (official postal service)).
• The union has given strike notices multiple times in 2025, most recently in May (Canada Post).

The dispute is in a “pause but not resolved” state. Each suspension buys time for negotiations, but without a ratified contract, any resumption of strike action is still possible.

What does Canada Post rotating strike mean?

A rotating strike is a targeted, short-duration work stoppage at selected facilities rather than a full shutdown of the entire postal network. CUPW announced the shift to rotating strikes on October 11, 2025 (CP24 (Canadian 24-hour news channel)).

How is a rotating strike different from a full strike?

• Full strike: all CUPW members stop work simultaneously, halting mail processing nationwide.
• Rotating strike: different facilities walk out on different days, so some mail continues to move while other regions face delays.
• CUPW described the rotating strike as an “escalation” that allows pressure while leaving some service intact (Labor Notes (independent labor journalism)).

Which locations are affected today?

• The union does not publish a daily schedule of which sites will be struck, creating unpredictability.
• Canada Post advises that delays vary by region, and that some facilities may be operating normally while others are idle (Canada Post (official postal service)).
• In November 2025, the rotating strike suspended all processing of unaddressed flyers (Wikipedia (community-edited encyclopedia)).

The pattern: rotating strikes turn mail delivery into a game of chance. One day your package moves, the next it sits in a processing centre that’s on strike. The lack of a predictable schedule makes planning nearly impossible for businesses and individuals alike.

Can I still receive mail during a Canada Post strike?

Yes – but with significant delays. Canada Post states that “mail and parcels are being accepted and delivered, but delays are expected” (Canada Post (official postal service)).

Will parcels be delivered?

• Parcel delivery continues, but processing may be halted at facilities affected by a rotating strike.
• Canada Post has warned that service guarantees (e.g., Xpresspost delivery dates) are not in effect during the dispute (Canada Post).
• International mail to Canada is also subject to delays; An Post (Ireland) has notified customers of ongoing rolling strike delays affecting Canadian deliveries.

Are all services stopped during rotating strikes?

• No. Unlike a full strike, many post offices and processing plants remain open on non-strike days.
• The union banned delivery of unaddressed flyers starting September 15, 2025 (Wikipedia (community-edited encyclopedia)).
• Collection and delivery of regular mail and parcels may still occur, but the Canada Post website recommends allowing extra time.

If you’re waiting for a time-sensitive cheque or package, the rotating strike means you cannot count on a standard delivery window. The only guarantee is that there are no guarantees.

When to expect mail Canada Post?

There is no single answer because rotating strikes hit different regions at different times. Canada Post says delays are “expected” for all classes of mail (Canada Post (official postal service)).

How long will it take for my item to arrive?

• No standard delivery time estimates are available during the dispute.
• Canada Post’s tracking system may show items “delayed” without a revised date (Canada Post).
• The rotating strike adds 1–5 days to typical delivery windows, depending on the region and which facilities are affected.

Are there any service guarantees during the strike?

• No. Money-back guarantees are suspended for all expedited services.
• Canada Post’s official stance: “Service disruptions may result in delays, and we cannot guarantee delivery dates” (Canada Post (official postal service)).

You can still send and receive mail, but you’ll have to plan around uncertainty. For essential documents, consider using courier services that are not part of the dispute.

Did Canada Post reach an agreement?

Yes – twice. The first tentative agreement was announced on December 17, 2024, but members never voted on it. A second tentative agreement was reached on November 21, 2025, leading to suspension of rotating strikes (Wikipedia (community-edited encyclopedia)).

What was in the tentative agreement?

• Details have not been fully disclosed, but the agreement addresses wages, job security, and working conditions.
• The Canada Industrial Relations Board (CIRB) had earlier extended contracts and ordered a 5% raise implementation (Labor Notes (independent labor journalism)).
• The union’s main concerns include the government’s plan to end door-to-door delivery for 4 million addresses and lift the moratorium on rural post office closures (Labor Notes).

Why are rotating strikes still happening?

• The rotating strikes that began September 2025 were a response to government reform announcements, not a failure of the first tentative deal.
• The second tentative agreement paused those rotating strikes, but ratification has not yet occurred.
• If members reject the deal, strike action could resume at any time.

Agreements have been reached, but they have not ended the dispute. The core issue – government-directed restructuring of Canada Post – remains unresolved. Until a contract is ratified, the possibility of more strikes hangs over every delivery.

What’s Confirmed and What’s Still Unclear

What the union and Canada Post have said

“We have agreed that all strike/lockout activity is suspended.”

Canada Post official statement, December 2024

“Today, September 15, postal workers across the country are escalating their strike action against Canada Post.”

CUPW bulletin, September 2025

The two quotes capture the whiplash of this dispute. One day pause, the next escalation. The pattern is clear: neither side is willing to give ground on the structural reforms that threaten tens of thousands of jobs (Labor Notes (independent labor journalism)).

Summary: What the rotating strike means for you

Canada Post is losing roughly $10 million per day as of September 2025 (Global National (Canadian TV news)). The government’s push to end door-to-door delivery and close rural post offices has turned a labour dispute into a political battle. For any Canadian waiting on a cheque, a passport, or a holiday parcel, the choice is clear: either plan for delays of a week or more, or use an alternative carrier. The rotating strike strategy means that even when mail flows, it does so unpredictably – and that uncertainty won’t end until a contract is ratified.
