Canada Post’s holiday peak-season rules are now in effect, narrowing late-delivery guarantee claims and increasing several handling surcharges for parcels mailed during the busiest shipping period.
The carrier’s notice covers services used under a Canada Post customer agreement and applies to items mailed from Monday, November 2, 2026, through Sunday, January 10, 2027. The peak-season delivery guarantee modification applies to Priority™, Xpresspost™ and Expedited Parcel™ services mailed within Canada. During that window, late-delivery claims for those services will only be honoured if the item is delivered two or more business days after the delivery standard.
The change modifies the claim threshold rather than removing every domestic guarantee outright. Canada Post’s broader Parcel Services Customer Guide says the On-Time Delivery Guarantee offers replacement service or a credit equivalent to shipping charges when published delivery standards are not met, but it also says the guarantee may be modified during a peak period.
Canada Post’s delivery standards page adds that delivery standards are calculated in business days from the next business day after deposit to the first delivery attempt. The standards exclude the mailing day, weekends and statutory holidays. Items deposited on a weekend, statutory holiday or after local cut-off times are treated as deposited on the next business day.
Service
Peak-season late claim treatment
Priority within Canada
Claim honoured only if delivered two or more business days after the delivery standard.
Xpresspost within Canada
Claim honoured only if delivered two or more business days after the delivery standard.
Expedited Parcel within Canada
Claim honoured only if delivered two or more business days after the delivery standard.
Regular Parcel
Canada Post’s guide says the On-Time Delivery Guarantee is not offered for Regular Parcel.
Canada Post’s terms also allow the On-Time Delivery Guarantee to be suspended because of causes beyond the company’s reasonable control, including inclement weather, transportation delays, labour disruptions, equipment failures and unanticipated surges in volume. Those exceptions sit alongside the temporary peak-period rule.
Three handling surcharges are higher through January 10
The same customer notice says Canada Post is adjusting three existing surcharges during the peak period. Oversize and Unpackaged items rise to $30 from $21, while Out-of-spec items rise to $400 from $300.
This is not described in the notice as a new blanket fee on every parcel. The higher charges apply to specific parcels that trigger the affected handling categories.
Surcharge
Regular amount
Peak amount
Canada Post trigger
Oversize item
$21
$30
Any dimension exceeds 1 m, or the second-longest side measures more than 76 cm.
Unpackaged item
$21
$30
The item is not fully encased in an outer shipping container, has excessively loose packaging, is irregularly shaped, cylindrical or round, or has contents protruding outside the packaging.
Out-of-spec item
$300
$400
The item exceeds Canada Post’s maximum size or weight specifications.
Canada Post’s packaging requirements page says the Oversize Surcharge and Unpackaged Items Surcharge are not combined. If one applies, the other is waived. The company’s size and weight restrictions page says an out-of-spec item may be refused, returned to the shipper or delivered at Canada Post’s discretion, with extra fees possible.
Fuel surcharge relief is separate from the peak handling fees
The peak notice lands at the same time as a separate temporary fuel surcharge relief program for eligible domestic parcels. Canada Post’s fuel surcharge page says a 15-per-cent discount is applied automatically to the published fuel surcharge from October 5, 2026, to January 3, 2027. The discounted fuel surcharge remains subject to a 25-per-cent minimum threshold.
Eligible domestic products listed by Canada Post include Priority, Xpresspost, Expedited Parcel, Expedited Parcel Plus, Day-old chicks, Regular Parcel and commercial prepaid products such as prepaid envelopes and labels.
Canada Post updates fuel surcharges weekly. As of November 10, 2026, the page lists domestic services for the week of November 9 to November 15 at 48.50 per cent before the temporary relief and 41.20 per cent after the temporary relief rate. For the same week, the listed fuel surcharge is 27.50 per cent for USA and International Parcel Services and 25.50 per cent for USA and International Packet Services.
For shippers, that means the peak handling surcharges and the fuel surcharge should be treated as separate cost lines. The temporary fuel relief can reduce one part of the bill for eligible domestic parcels, but it does not remove the higher peak charges for oversize, unpackaged or out-of-spec parcels.
The practical effect for holiday parcel planning
For businesses that quote delivery dates or shipping costs at checkout, the most useful immediate checks are:
Separate the delivery standard from claim eligibility. A published standard may still guide the estimated delivery window. A one-business-day delay during the peak period may not qualify for a late-delivery guarantee claim on the affected domestic services.
Measure parcels before rating and labelling. Crossing the oversize threshold can add a peak surcharge, and crossing the maximum size or weight rules can trigger a much larger out-of-spec charge.
Review packaging for bulky or irregular products. Unpackaged, loose, cylindrical, round or protruding items can fall into the higher peak surcharge category.
Check fuel surcharge rates weekly. The current domestic relief is temporary, while the underlying percentages still update by week.
