Horton is a township in eastern Ontario, Canada, at the confluence of the Bonnechere River and the Ottawa River in Renfrew County. The Town of Renfrew was originally part of Horton Township.
The township comprises the communities of Castleford, Castleford Station, Cotieville, Fergusons Beach, Goshen, Lochwinnoch (partially), Mayhew and Thompson Hill.

In 1891 the community name reverted to Castleford.The town of Castleford is the first of five chutes along the Bonnechere River. The others being Renfrew, Douglas, Fourth Chute and Eganville. The chutes used were for moving timber past rapids and waterfalls.
In 1889 the Castleford designation was also given to the CPR station at Castleford Station. Both communities were named after Castleford in West Yorkshire, England.
