What is the length of the shipping season on Lake Ontario?

The shipping season on Lake Ontario typically lasts about 6 months, which is a crucial timeframe for commercial shipping activities in the region. This duration is primarily influenced by weather patterns and ice conditions that develop during the winter months. Usually, the shipping season begins in late March or early April when the ice melts and ends in late November when ice begins to form again. This timeframe allows for the safe navigation of vessels, ensuring that shipping operations can be conducted efficiently and without significant delays caused by seasonal weather changes. The transition periods before and after this season are often marked by significant ice formation, which can hinder vessel traffic and necessitate the closure of shipping routes. Understanding the nuances of the Lake Ontario shipping season is vital for those involved in maritime commerce and navigation in the area.
