Iron Ore Company of Canada

Quebec, Newfoundland & Labrador

The Iron Ore Company of Canada (IOC) operations are integrated across a mine and processing plant in Labrador City, Newfoundland and Labrador; a port and stockpile in Sept-Iles, Quebec; and a 418 kilometre railway that joins these two parts of the operation.

IOC is a joint venture between Rio Tinto (58.7%), Mitsubishi (26.2%) and the Labrador Iron Ore Royalty Income Corporation (15.1%).

  • Older pit at IOC
    One mine in Labrador City with five operational pits with significant deposits for the supply of high-grade iron ore products.
  • Truck convoy at IOC
    Our processing centre includes a concentrator and a pellet plant allowing us to transform our ore into high grade iron ore products.
  • Port facility at IOC
    One port facility in Sept-Illes from where our products are shipped to customers around the world.
  • Train running past meadow
    Rail Network
    We operate a wholly-owned 418 km railway, the Quebec North Shore and Labrador Railway (QNS&L) that links our Labrador operations to our port facilities in Sept-Iles.

Innovation at IOC

The fully integrated operation at IOC is supported by two operations centres in Labrador City and Sept-Iles that allows us to ensure our mine, processing operations, port and rail system work together efficiently to achieve maximum productivity.

The rail network is the link between the two parts of our operation and all of our rail traffic is managed in real time using state-of-the-art technology and the latest computing, railway communications and signalling protocol technologies.

Our dispatchers have a full view and control of all rail traffic helping to support the safe, reliable and smooth running of our trains and in turn of our integrated operation.

The mining industry is continuing to grow and evolve, so effective utilisation of our assets is critical for us to remain competitive, reach our full potential and lay a solid foundation for our future.

In 2019, IOC made the decision to move forward with concentrate and pellet plant remote operations, the next step in our journey to help ensure a strong future for our business and our communities.

Our team continually innovates to improve safety and production, like pioneering a drill bit changer that can easily lift, handle and move around the tools required during a drill bit change-out, to keep people out of the line of fire.

Moss pit at IOC
Moss pit opened in 2018


We have a high-quality iron ore reserve and long mine life. In 2018 we opened a new pit, the Moss pit, at our existing mine site in Labrador. This development will extend the life of our IOC operation, reduce operating costs and sustain production of our quality grade iron concentrates and pellets.

Our high-grade, low impurity products, within the broader iron ore market, have seen a significant and sustained increase in demand from steel producers.

Building a Better Future Together

Together with the Innu communities of Uashat mak Mani-utenam and Matimekush-Lac John, in Newfoundland and Labrador and Quebec, Canada, we signed a new partnership agreement called “Ussiniun” in December 2020. 

IOC, Canada


In the Innu language, the word “ussiniun” means “renewal.” Through this partnership, we will build a stronger future together – supporting local education, jobs, the environment, and work to preserve the unique customs and cultural practices of both communities.
