BOATsmart! Base de connaissances du Canada 

The Collision Regulations require that boaters be aware of shipping lanes (traffic lanes) and use extreme caution when near vessel traffic lanes. Large commercial ships often cannot see small pleasure craft operating ahead of them from the bridge. You should always proceed in the appropriate traffic lane in the general direction of traffic flow for that lane. Boaters should join or leave a traffic lane at its termination, but when joining or leaving from either side you should do so at as small an angle to the general direction of traffic flow as practicable.

You should avoid crossing traffic lanes but if you must, cross at a right angle to the general direction of traffic flow. If navigating near a shipping lane or near the termination of a shipping lane you should use caution and avoid the lane with as wide a margin as practicable. Always avoid anchoring in a shipping lane or near its termination. To increase your visibility to larger vessels in or near a shipping lane, you should stay in groups with other small boats, if possible.
