This activity is one of a series of 17 teacher-developed instructional activities for geography at the secondary-grade level described in SO 009 140. This activity is a report or case study which looks at the implications, problems, and reactions to a regional comprehensive plan to regulate growth patterns in a 15,000 square-mile area of Toronto, Ontario. In May 1970 the Ontario government, drawing on the results of joint citizen and government studies, issued its Design for Development: The Toronto-Centered Region. The report lists the design's five development principles and 12 regional goals which are the basic guidelines for all government decisions concerning the region. The report then goes on to list the existing trends and development problems in the Toronto area which, if not altered, will impede the attainment of the design's principles and goals. Specific recommendations made by the Ontario government to attain the design's objectives and to counter the trends and development problems are then outlined. Five maps are included with the report.
