One comment that I often hear about interprovincial trade barriers is that it's the nitty-gritty, tiny details like the specs for fire extinguishers on trucks, axle weights and so on. This just makes it an unattractive thing to tackle.
My response is that this is where the payoff is. For the federal government to take the lead when it comes to compiling the information, sharing the information and then of course using its power to lean in sounds like a good idea. I don't know the specific proposal you're referring to, but I do want to underline that some of this work is not very glamorous. Some of it is very technical, but that's the level on which you need to proceed if you really want to make headway in this area.
The federal government can look at its own measures that sometimes fragment the internal market. It'll often follow provincial rules that it doesn't need to follow. Supply management came up earlier. There, you have a fragmentation of the internal market that the federal government supports. I know that's a very delicate one.
The federal government itself can do a number of things. Anything that helps us through that massive technical detail, I think, has to be helpful.
