Environment Canada's Inspection for In-Use motor

Demonstration inspection and maintenance programs in major cities across Canada have indicated that the full effectiveness of emission control equipment installed on new cars is not being achieved as a result of improper vehicle maintenance or tampering with the control devices. Environment Canada has recognized this phenomema as being both a technical and a social problem.

In order to implement an effective solution while avoiding negative public response, a different type of program is proposed in which the mandatory annual inspection will apply initially to new vehicles only such that the fleet subject to inspection and maintenance will be “phased-in” gradually.

The methodology of such an approach is explained in this paper.
