 On June 5 , 1799 , Asa Danforth Jr. began construction eastward from Toronto on a road which was to extend the Governor 's Road through Port Hope and to the Trent River . That road , completed in 1801 , would be described by acting surveyor general William Chewett to be " good " for use in the dead of winter but " impassible " during the wet summers , when the path turned to a bottomless mud pit . It would be extended in 1802 to reach the Bay of Quinte at Stone Mills ( now Glenora ) and a ferry crossing established to Adolphustown . The Bath extension of the Danforth Road ( 1802 ) provided access to a key early colonial road , the Bath Road , which had long joined Bath to Kingston .
