Thank you very much, Mr. Chair.
My first question is for Mr. Baruchel. I'm from the north shore, opposite Montreal, and Mirabel is located in my riding. I've seen first hand the quality of your work on aeronautics systems.
I'd like to talk about rail signaling. Is your work around the world advanced enough for you to tell us what percentage of the total installation cost can be attributed to signaling, or must each situation be analysed individually, because each one is different?
The Quebec-Windsor corridor is approximately 1,200 kilometres long. You have no qualms about installing signaling over 1,200 kilometres of track. Do you know in advance what signaling represents as a percentage of the overall cost of a rail line?
