For all shipments handled by CN Truckers:

Spring Weight Restrictions - 2016

To all Customers shipping to/from the Province of Quebec. Please visit their website for the geographical limits of their zones and for any updates or modifications to the dates.


Zone 1: Monday, March 14th to Friday, May 13th
Zone 2: Monday, March 21st to Friday, May 20th
Zone 3: Monday, March 28th to Friday, May 27th

Please note that payload weights in equipment to be delivered by CNTL must be reduced per the requirements below for shipments planned to arrive after the start of their Spring Weight Restriction period.

To assist its customers during this period of reduced payload:

CN will establish a "Latest Shipping Date" where customers may ship at regular payload weights from each terminal (based on the consignee receiving the traffic immediately upon arrival at the destination terminal).

Note the "Date" will be the Reservation Date, not necessarily the date the shipment is released by the shipper. CN’s online tools can assist in determining the Reservation Date and Trip Plan.

CN will use specialty equipment to deliver any load that is overweight after receiving written confirmation that the payer understands the charges. Charges for this service are per tariff CNR-9100 ($600 premium per delivery). To ensure the specialty equipment is not detained, all deliveries must be live-unloads.

The timing of delivery of overweight loads will be governed by demand. As such, normal extended use of asset fees (per tariff CNR-9100) will apply.

Overweight traffic delayed online, but shipped prior to “Latest Shipping Date”, will be delivered by CN without the application of the charge in tariff 9100.

The following table shows the "Latest Shipping Date" relative to the start of the Spring Weight Restriction as established by the province of Quebec:
