Little Bras d'Or is a tidal channel in Cape Breton, Nova Scotia, connecting Sydney Harbour to the Bras d'Or Lakes. It serves as one of three entry points into the Lakes system and is the preferred passage for many power boats transiting between Sydney Harbour and the Lakes. The channel is navigable by small craft with a draft of less than 10 feet and an air-draft of less than 21 feet, which are important considerations for paddlers sharing the waterway with motorized vessels.

The seaward entrance to the channel can be impassable in heavy seas due to breaking waves, particularly when wind opposes the tidal current. Paddlers should exercise caution at the ocean-side entrance and plan passages with attention to both weather and tidal conditions. The channel carries tidal flow, which will affect paddling effort and timing depending on direction of travel.

A single-span bridge, which replaced an older road bridge in 2013, crosses the channel. The relevant Canadian Hydrographic Service charts for this area are CHS Chart No. 4267 (Little Bras d'Or) and CHS Chart No. 4277 (Great Bras d'Or, St Andrews Channel & St Anns Bay). There are numerous public launch ramps in the broader area for those trailering boats to the water.

Limited amenities are available locally, with a gas station providing fuel and limited food supplies near the channel. More extensive provisioning can be found further into the Lakes system; for example, the Orangedale area on Bras d'Or Lake offers food, gasoline, ice, water, and dockage. The Little Bras d'Or channel functions primarily as a transit corridor rather than a destination paddling area in its own right, and paddlers using it should be prepared for boat traffic and variable conditions at the tidal entrance.
