As an organization, we knew that mandatory screening with RBT had been very effective in other jurisdictions. We wanted to make sure that it would respect our charter here. That's why we did our own legal analysis. Then we sent that to Peter Hogg for his own interpretation of it, and it was only at that point in time that we felt very comfortable.
Will it get challenged? Absolutely. Parliament is going to have to depend on section 1 for sections 9 and 10(b) of the charter. On section 8, with the searches at airports, and so on, nobody has ever challenged it. I think there's no real question about any charter infringement there, and the court's decisions in the past have been very strong on road safety, public safety, especially when it comes to impaired driving. We have no doubt that it will be challenged, and we have no doubt that it will be upheld.
