The Metropolitan Toronto Planning Board’s water supply plan reproduced from the Board’s 1965 draft Offical Plan for the metropolitan planning area. The West Credit lands are still unserviced, and would remain so until the ‘South Peel Scheme’ was built early in the 1970s.

The Metropolitan Toronto Planning Board’s Plan for regional sewer services, reproduced from the Board's 1965 draft Official Plan for the metropolitan planning area. The plan did not call for any lake-based service to Brampton; these would not come until the ‘South Peel Scheme’ of the early 70s.
