R. v. Sault Ste. Marie, [1978] 2 S.C.R. 1299
A leading decision on the classification of regulatory offences and the due-diligence defence. Its application depends on the wording of the offence and the evidence in the specific file.
R. v. Ladouceur, [1990] 1 S.C.R. 1257
The Court considered arbitrary detention during a random traffic stop and its justification. The decision does not, by itself, determine whether a particular stop was lawful.
R. v. Jordan, 2016 SCC 27, [2016] 1 S.C.R. 631
A leading decision on section 11(b) of the Charter. Delay calculations include exclusions and exceptions; application to a provincial penal matter must be assessed case by case.
A recent decision will be added only after checking its official source, appeal status, limited holding and actual relevance to Quebec traffic law.
