I'm just a fertilizer guy.
The economy works together best when businesses collaborate, and there are a lot of players in the whole supply chain that moves products in and out of Canada. Obviously, having forecasts of what we're going to be doing with our business and where we're going is important, and we hope that the railways react to that. I think sometimes the railways have delayed making investments in infrastructure until the volume is there.
Our industy in potash, in particular in the province of Saskatchewan, has invested about $18 billion in increasing its capacity. That's an important signal to the marketplace, to the ports, to ocean freight, to the railways that our industry is growing and that we need more capacity in the system. We hope the railways would respond to that.
There are constraints in the system because of geography. We understand that. We know that there's an aggressive program of infrastructure improvements at the Port of Vancouver that's being proposed. We'd like to see the government get behind that, for example. I don't think there's a simple answer to that.
I'd just like to ask if the chair would allow Mr. MacKay to respond briefly regarding the North American network.
