The Havelock subdivision was built by the CPR as the Ontario & Quebec railway from Glen Tay to Toronto in 1884.
Long after abandonment of the rails beyond Glen Tay (through Tweed by 1971 and then to Havelock in 1988), the Trans Canada Trail occupies the rail bed from Sharbot Lake to Bonarlaw where the Trans Canada Trail turns south on the Hastings Heritage Trail and the former Maynooth subdivision.
