Okay. You mean what we're calling “multi-jurisdictional challenges”, as opposed to an ad campaign.
Yes, multi-jurisdictional challenges affected the timelines of several of the measures; however, the federal government does not have to keep consulting until they reach consensus. They do have the constitutional jurisdiction to enact regulations under CEPA and to enact a price on pollution under the Greenhouse Gas Pollution Pricing Act.
Consultations shouldn't just keep going forever until a consensus is reached. At a certain point, a government has to make a decision.
