Additional Lighting Requirements

Besides navigation lights, Ontario's boat light laws also dictate the use of other lights for specific purposes:

Masthead Lights

Vessels over 7 meters (23 feet) in length must display masthead lights, which are positioned at the highest point of the vessel. These lights help other boaters determine the size and type of the vessel they're approaching.

Masthead lights consist of:

  • One all-round white light visible from 360 degrees.
  • One red light and one green light, visible from forward of the boat, indicating its direction of travel.

Sidelights and Sternlight

Vessels over 12 meters (39 feet) in length must display sidelights and a sternlight in addition to masthead lights. Sidelights help other boaters determine the vessel's direction of travel, while the sternlight indicates its position relative to other vessels.

Sidelights and sternlights consist of:

  • Two red lights, one on each side of the vessel's stern, visible from forward of the boat.
  • Two green lights, one on each side of the vessel's stern, visible from forward of the boat.
  • One white light at the vessel's stern, visible from astern (behind) the boat.

Staying informed about Ontario's boat light laws is not only essential for your safety but also helps maintain the enjoyment and tranquility of Ontario's waterways for everyone. By understanding and adhering to these regulations, you contribute to a safer and more pleasant boating experience for all. So, the next time you set sail under the Ontario sky, make sure your vessel is properly lit and ready to navigate the waterways safely and responsibly.
