“Based on our research and collision investigation programs, Transport Canada has not identified a pattern of motor vehicle collisions caused conclusively by tire failure in Canada,” the agency said.
“However, we continue to monitor the effectiveness of TPMS to determine if they provide any potential safety benefits to Canadians and will take action as required.”
Meanwhile, rules about the use and maintenance of TPMS would fall under the jurisdiction of Canada's provinces, just as regulations about vehicle operation and licensing would, Transport Canada said.
However, no Canadian province has established rules about TPMS. OTDA President Mike McClory wrote Ontario Minister of Transportation Steven Del Duca in May 2015, asking the provincial agency to establish best-practice guidelines for TPMS.
“Given that the majority of vehicles on Ontario roads have TPMS, issues of risk and liability arise as a result of the lack of regulatory clarity regarding the aftermarket management of TPMS,” Mr. McClory wrote.
In a July 2015 reply, however, Mr. Del Duca said his agency would not issue any TPMS guidelines.
“Given that Transport Canada has determined that there is not a safety-related need for TPMS in Canada's fleet of light-duty vehicles, the Ministry of Transportation has aligned with this position,” Mr. Del Duca wrote.
“As a result, no consideration has been given regarding the requirement of the retention or functionality of TPMS in Ontario's vehicles,” he wrote.
The tire and wheel section of Ontario's Light Duty Vehicle Inspection Standard, which was issued in October 2015 and will become effective July 1, 2016, does mention TPMS. Under that standard, the inspector must record on the report if the TPMS warning light is illuminated during operation. However, such illumination is not in itself grounds to reject a vehicle.
As with other tire-related associations, the OTDA strongly recommends checking tire pressures at least once every 30 days.
