CPKC Vaughan Intermodal Terminal and CN MacMillan Yard Are Not the Same Facility

Vaughan hosts two major rail facilities that are often mixed up in conversation. They serve different functions — which matters when you are trying to understand truck traffic and fleet scheduling around either one.

Updated: July 17, 2026

Where CPKC Vaughan Intermodal Is Located

The CPKC Vaughan Intermodal Terminal is located in west Vaughan between Rutherford Road and Major Mackenzie Drive, near Huntington Road and Highway 50. It is separate from CN's MacMillan Yard in the Concord area. The City of Vaughan describes the facility as sitting between Rutherford Road and Major Mackenzie Drive, and between Huntington Road and Highway 50.

What an Intermodal Terminal Does

An intermodal terminal transfers shipping containers between trains and highway tractors. That container-focused activity generates rail-to-truck drayage traffic. The City of Vaughan has described CPKC Vaughan as a major containerized-goods facility connected to nearby highway systems; it is commonly identified as CPKC's largest intermodal terminal in Canada.

What CN MacMillan Yard Does

CN's MacMillan Yard, in the Concord area of Vaughan, is primarily a rail classification facility: rail cars are sorted and reassembled into outbound trains. CN materials and Transportation Safety Board reports describe MacMillan as CN's main classification yard in Eastern Canada, with hump and flat-switching operations. The City of Vaughan has also referred to it as CN's second-largest classification yard. MacMillan Yard is primarily a rail classification facility, so its road-vehicle activity differs from the container-focused drayage traffic associated with CPKC Vaughan Intermodal. MacMillan may also support repair, bulk-handling, service and other rail-related vehicle movements.

How Their Truck Traffic Differs

CPKC Vaughan Intermodal generates substantial rail-to-truck container activity. MacMillan Yard primarily supports rail classification, switching, repair and related freight operations. Commercial vehicles working around the two facilities may therefore have different routes, site-access requirements and duty cycles. Do not assume that every truck near MacMillan is running the same container-gate cycle as a CPKC intermodal tractor.

Which Vehicles Need DriveON Testing

When a DriveON emissions test is required

A heavy-duty diesel commercial motor vehicle with a Registered Gross Weight (RGW) over 4,500 kg needs an emissions test when it is being registered by a new owner and the vehicle is older than the current model year, or when it is at least seven model years old and the plate sticker is being renewed.

When On-Site Testing May Be Practical

An authorized mobile DriveON facility and registered DriveON technician can inspect prepared units at an eligible fleet yard when safe access and suitable testing conditions are available. The inspection standard does not change because the test happens on-site. Related guides: CN MacMillan Yard corridor and Concord / Hwy 400–407 fleets. Book through Piotr Service.
