Where To Start

How It Works

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.

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.

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.

Apply for a large vessel move

The application to move large vessels requires the following information:

• Clear maps of intended route to destination – we recommend using Google Maps
• All structure and equipment information
• Start and end dates including specific times of transport
• Detailed address and information for end point, drop-off points etc.

To apply for a Large Vessel Move, please mail, email or fax your completed form to:

Hydro One Networks Inc.
1 Greendale Drive
Caledonia, ON N3W 2J3

Fax: 1-905-765-3663

Additional road permits for oversized loads can be obtained through the Ministry of Transportation’s website.
