The features, flaws, and effects of aging on Ontario's 8000Cs are therefore difficult to study. Crown scientists working for the Centre

Purpose: To suggest that ATC/CFS scientists cannot provide any scientific opinion of the reliability of aging instruments out in the field without conducting an empirical study of instruments sampled from the field. To suggest that ATC/CFS scientists have no idea whether or not instruments in the field are performing in accordance with manufacturer's specifications. To identify the lack of any system of "verification" in Canada that instruments in the field are performing in
