The Official Plan policies and CPP bylaw could be adopted years in advance of actual development applications, and other than notifying citizens of the various applications coming in, it is possible that there would be no further opportunities for public consultation in the affected area. Through the CPP, citizens get certainty by agreeing to a community vision up front - in return for being able to appeal individual development proposals that are in keeping with that vision. In this way, it allows for a municipality to require community benefits from the developer.
Moreover, the outcome of an application in a CPP area is not appealable by citizens to the new Local Planning Appeals Tribunal (LPAT). If the application is approved by the municipality, only the developer can appeal if the application is turned down.
The CPP system has been around for over a decade and originally was not used extensively, but seems to be attracting more attention in recent years. In the Greater Golden Horseshoe, at least Toronto, Brampton, and Ajax have CPP systems in place. Innisfil and Niagara-on-the-Lake are also currently exploring the use of a CPP system.
