I doubt it will.
The constitutional challenges hinged on HTA172 having 6 months in jail as a potential penalty, and with it being perceived as an absolute liability offence the same as speeding. The Court of Appeal knocked that peg out when they ruled that HTA172 was a strict liability offence that permitted an accused to mount of possible defence of due diligence, and that therefore HTA172 was constitutionally acceptable per those grounds.
The only other possible challenge would hinge on roadside administrative suspension and impound prior to trial, but the provincial right to impose such administrative measures in matters of provincial regulation (transportation as per powers granted to provinces under the British North America Act, aka the Canadian Constitution) was affirmed in back in 1999 in Horsefield v Registrar of Motor Vehicles Ontario http://www.canlii.org/en/on/onca/doc/1999/1999canlii2023/1999canlii2023.pdf
Unless you can think of another avenue in which to attack the constitutionality of HTA172, I think that ship has long since sailed.
Or a higher set of judges can rule that HTA172 isnt a strict liability offence that didnt permit an accused to mount a possible defence of due diligence.
