I'll address that for the north. It's not a veto per se, but beyond first nations, the aboriginal groups include Inuit in the north. In accordance with their land claim agreements, they co-manage environmental assessment boards. They have members on those boards. They have a large say in what happens in the regulation of oil and gas activities.
Under the Inuvialuit Final Agreement there was a major hearing by the Environmental Impact Review Board, for instance, in the early 1990s, which put up major questions on the operator's plan to drill. In essence, the operator did not go forth with that drilling program.
