There are important distinctions to make between Caron and Pooran.

Caron challenged his traffic ticket because it was not printed in both English and French. It should be noted that most of the proceedings in that case were argued in French before the various levels of the Alberta Courts, but that was not the issue. As things now stand, Caron's conviction stands and his language-based defence (i.e. English only ticket) has not yet been accepted by the higher Courts.

Pooran's challenge concerned the use of French in the Alberta Courts in such a way as the ensure that that language may be used in the most complete manner possible. Pooran's position was accepted by the judge. It would seem that as no appeal was filed by Alberta, that this one may have settled the question quite simply.

Caron's challenge goes further than Pooran/Vaillant.

Neither of these interesting cases has anything to do with WS, which is an airline that is subject to Federal rules regulating that industry. We also know that AC, an airline, is obligated to follow an additional set of rules arising from the ACPPA and the OLA. Those rules do not apply to WS.
