The channel between the mainland and which island is broad, deep, and is occasionally used by tows bound to and from the St. Lawrence River?

The channel between the mainland and Stony Island is notable for its broad and deep characteristics, making it suitable for navigation by larger vessels, including tows that are traveling to and from the St. Lawrence River. This specific channel is part of the navigable waterways utilized for commercial shipping and transportation. The depth and width are significant for ensuring safe passage for such tows, accommodating their size and draft, which is essential when navigating in proximity to various islands and the mainland.

While other mentioned islands may have channels, they do not possess the same navigational attributes required for regular tow operations, which adds to Stony Island’s distinction in this context. This attribute is particularly relevant for maritime operations in Lake Ontario, where safe and deep waterways are critical for transportation.
