The Northern Railway of Canada was a railway in the province of Ontario, Canada. It was the first steam railway to enter service in what was then known as Upper Canada. It was eventually acquired by the Grand Trunk Railway, and is therefore a predecessor to the modern Canadian National Railway (CNR). Several sections of the line are still used by CNR and GO Transit. * Craigleith Station - restored and now a museum * Thornbury Station - now a retail store on Highway 26
