2.2 What is a Tracking History and is it required for a speeding charge?
[12] Exhibit 1 sets out page 30 of the Genesis-VP User’s Manual. This manual is a product of the manufacturer of that particular radar unit. It states:
6.4 Tracking History
For each enforcement action taken by the police with respect to a speeding offence arising out of the use of this radar unit a tracking history must occur. The tracking history shall consist of:
1) A Visual Observation of an approaching or receding Motor Vehicle that appears to be in excess of the posted speed limit in the area and an estimation by the officer of the speed of that motor vehicle is traveling. Generally, skilled officers are able to estimate the speeds of moving motor vehicles within plus or minus 5 Km/H per hour of the actual speed. This is an acquired skill that is taught on the basic operators course.
2) Having made the visual observation and estimate of the rate of speed, the radar unit will be placed in the operational mode.
3) Note, that the target displayed on the radar unit is consistent and confirms the officers initial observations and estimate, and that the audio tracking tone emitted by the radar unit is consistent with the visual observations and the target speed displayed.
4) Absence of any one of the above tracking history components and NO ENFORCEMENT ACTION shall be undertaken.
[13] It is clear from the Tracking History description in Exhibit 1 that the position of the manufacturer is an officer may not lay a speeding charge unless all of the components of the tracking history exist.
[14] There is case law that illustrates the importance of a tracking history. In
R v Desgagne, [1997] A.J. No. 1307, Constable Parsons of the Royal Canadian Mounted Police (RCMP) gave evidence on a speeding charge. Cst Parsons was a certified instructor for the RCMP in radar. At the time of the offence he had over 10,000 hours of operation of radar. The constable was operating what was described at paragraph 189, as a ‘Decater Genesis’ radar unit, which I understand to be similar to the radar unit, in the case at bar.
(NB: This Court believes the correct spelling of the manufacturer’s name is Decatur).
[15] Cst Parsons, in paragraphs 180 through 198 of
Desgagne, described his actions in maintaining a tracking history with elements similar to those of Exhibit 1, on a target motor vehicle prior to laying a speeding charge. Having accepted the evidence, Reimer J., convicted Mr Desgagne of the offence of speeding.
[16] From
Desgagne, I draw the following conclusions:
(a) A tracking history is considered to be a necessity by a very experienced RCMP radar instructor before laying a charge, when operating a Genesis radar speed detection device.
(b) The evidence of the tracking history was a requirement to satisfy the Court that the Crown had proven its case, beyond a reasonable doubt.
[17] A plain reading of the Tracking History in Exhibit 1 indicates to this Court that the tracking history provides one final test to ensure the operator that the unit is functioning accurately. In support of this view, I note that the Tracking History requires that once the unit is placed in operational mode, then the operator must ensure ‘that the target displayed on the radar unit is consistent and confirms the officers initial observations and estimate, and that the audio tracking tone emitted by the radar unit is consistent with the visual observations and the target speed displayed’
. Only then can enforcement action be taken.
[18] In my view, an officer operating a speed detection unit, for which the device’s manufacturer requires a tracking history, is obligated to follow this part of the manufacturer’s instructions, as well as all others.
[19] I note that the prosecution did not take a contrary position on this issue.
