Canada: customs threshold, transit and surcharge months

Duty treatment is the first thing that changes when the destination changes, the transit tail is the second, and base freight is the third. What does not change is the shape of the weight-band tariff, which is the same on all four lanes. Canada shares the US — Economy lane with United States for freight and transit, so those figures are reused rather than duplicated — the customs treatment is what differs.

open window · peak surcharge · tight window. States come from published carrier announcements; a cell with no announcement is marked open, which is not the same as cheap.

Surcharge: A published peak-season surcharge applies to express services in that month for that region.
Tight: No surcharge is published, but transit in our sample runs longer; the grid states how many days earlier to ship.
Open: No published surcharge and no measured lengthening. It does not mean the cheapest month of the year.

Customs and declared value

Canada — threshold behaviour
Item	Treatment in our model
Threshold	The US publishes a de minimis threshold below which no duty is collected on most consumer goods; entries under roughly $200 in our sample showed no charge. Verify the current figure before relying on it.
Compensation ceiling	Equals the declared value on every destination — the ceiling and the duty are anchored to the same number
Below threshold	No duty modelled; the declaration still sets the ceiling
Above threshold	Modelled range of $0.00–$17.40 across the census, varying by product type

Modelled from published thresholds. This is not tax advice; verify the current rules for your destination before relying on a figure.

Transit to this destination

Bands show the p10 to p90 span for each stage; the solid tick is the median and the open circle marks where the slowest tenth begins. Sample size is printed per stage.

Reading the band: A narrow band means the stage is predictable; a wide one means the outcome depends on something you may control.
Tail triggers: A seller who does not confirm the order within 24 hours is the single largest cause of a slow start. Warehouse queues around a public holiday push this stage past four days. Consolidation requests submitted after the parcel is already packed restart the clock.

A worked $400 bill

$400

lands 6–10 items

Cost breakdown for the $400 budget rung
Item value	$21.30–$76.22
Domestic delivery	$0.40–$3.10
Service fee	$1.20–$9.80
International freight (compressible)	$5.90–$41.50
Duty (compressible)	$0.00–$17.40
Insurance	$0.00–$2.60

Midpoint total about $89.71 before item value is chosen. Punched rows are the compressible segments.

Most likely to overrun: Duty is the segment to watch here. Declared value is high enough that a single mis-stated figure can add more than the entire service fee.

Three things that surprise people here

Canada — the three most common surprises
Surprise	Why it happens
The estimate omitted duty entirely	Duty depends on the declaration and the destination, both of which the payment flow treats as later decisions. Its absence reads as zero.
The transit tail is longer than the median suggests	The p90 on this lane is 40 days against a median of 20.
Freight changed after packing	Volumetric weight is measured on the packed parcel, and a packed parcel is bigger than an unpacked one.

None of the three is specific to this destination, but all three show up more often on longer lanes.
