Transporting a large vessel across our service territory? You're likely travelling through parts of our Transmission or Distribution network. In order to ensure safe, uninterrupted travel that does not affect our network, you'll need to arrange a Large Vessel Move.

Based on the size of your load, we may be required to raise lines, disconnect lines, or make changes to infrastructure to provide adequate clearances for safe transport.​

Large vessel parameters

If your over-sized load is in excess of 14.2 feet (4.32 meters) high you'll need to arrange a Large Vessel Move. This helps ensure your safety and that our infrastructure is not damaged and does not becomes an impediment to you while in transit. The safety and reliability of Ontario’s Transmission and Distribution networks depend on it.
