It may be useful to think of three types of air transportation: international transportation from one country to another; what we've called “interjurisdictional”, say from Yukon to Northwest Territories or Ontario to Quebec, so from one jurisdiction in Canada to another; and intrajurisdictional.
International aviation is going to be subject to carbon pricing starting in 2020 under a regime that Canada has signed onto, which was negotiated under IATA, the international aviation association. All of the large countries and major airlines in the world have agreed to be part of this system. It was essential that it be an international system because, as you can imagine, it would be difficult for one jurisdiction alone to put a price on international aviation fuels—airlines would simply fill up their planes somewhere else.
Canada was part of the negotiation of the system. This will apply in 2020, so for that reason neither any provincial nor the federal backstop system applies to international transportation.
Interjurisdictional transportation—from province to province or territory to territory—is not covered at the moment. What Ministers McKenna and Morneau have said is that they intend to address this gap. They have not decided how to address it.
The reason it's a gap is that no jurisdiction currently addresses interprovincial or interterritorial flights. This may be the one area in which the federal backstop applies beyond just in provinces that don't have a pricing system. We may need the backstop to apply also in provinces that have a pricing system but that do not address interjurisdictional aviation.
This would be complicated in your jurisdictional discussion. The decision was to get this system up and running and then to start those discussions.
I was in Yellowknife last week talking with the deputy minister of finance and made a commitment to the territory's deputy of finance and environment that they would be involved in those discussions and that one option—making no commitment as to the outcome, because that will be politically decided—clearly could be to have a different system for interjurisdictional travel between provinces and interjurisdictional travel going to the territories. At the moment, none of those flights is priced.
Intrajurisdictional aviation fuel is priced under the backstop system. It's something that can be completely controlled by the backstop or by an individual province and, consistent with the government's policy that pricing should apply to a broad suite of activities, it is included in the backstop system.
The final point I'd make, though, is that we're also in extensive discussions with each of the three territories about offering the services of the Canada Revenue Agency to provide whatever rebate system each territory wants to implement in order to address, for example, impacts of increased aviation costs upon households in remote communities, if the territorial government so chooses.
