Thank you, Mr. Chair.
I want to welcome all the witnesses.
Mr. Barrieau, your remarks were very interesting and covered considerable ground. I hope I have time to get to all the things I want to talk to you about.
In a Radio-Canada interview in July 2021, you said high-frequency rail would pave the way for high-speed rail. That was interesting because it is at the centre of our current discussion, as we are wondering whether we should choose high-frequency rail, high-speed rail or a combination of the two.
A question came to mind that you might be able to answer. Why should we invest tens of billions of dollars in high-frequency rail, knowing that we will have to start over again in 10, 15, 20, 30 or 50 years for high-speed rail? Considering how long it will take for high-frequency rail to be operational—it will not be available for 10 or 15 years—is it realistic to think about starting over again to create high-speed rail? What are your thoughts on the roll-out of all of this?
