McNab rests upon the steady, sloping earth of the Palatine Hill, offering a quiet perspective over the expansive waters of Lake Ontario. It lies 9.0 km north-east of St. Catharines, ON (from St. Catharines, ON: bearing 42°T), and is situated 4.8 km west-north-west of Niagara-on-the-Lake. The air here holds a crisp, persistent moisture that seems to rise directly from the Welland Canal, cooling the skin even in the height of summer. Life in McNab moves with the purposeful utility of the canal, an artery that has long defined the local economy and the heavy, mechanical pulse of the passing ships. While the modern world presses forward, the land retains the dignity of its agricultural foundations, marked by the long shadows cast across the fields as the sun dips behind the ridge. DeCew Falls, located about 15 km away, serves as a distant, rushing reminder of the power inherent in these slopes, a silent companion to the more measured, industrious pace that defines the daily lives of those who call McNab home.
