Thank you, Chair.
First of all, I'd like to say to all the witnesses today that you've made your positions incredibly clear. You've communicated your anxiety and your frustration, particularly about the length of time it's taking to get you the assistance package that our government has committed to.
One thing I've learned as a member of this committee is how complex the aviation sector is. We have so many representatives here today, and we had many on Tuesday as well. We really want to make sure the concerns of all parties are addressed in that assistance package, and you have made absolutely clear the devastating effect that the pandemic has had on you.
My first question is for Mr. Best.
Mr Best, you've talked about service-level changes being proposed by Nav Canada, and I was wondering what kind of role Transport Canada has when service levels are proposed to be changed. Could you elaborate on how the process works?
