Thank you. Well, again, Tracy will have to share with you very soon some of our vision. But I go back to when Claude became CEO at that time, I became Chief Marketing Officer. And at that time, we had made enough progress on the operation that we had find a way to make better use of the network, and we grew the RTM and the volume very solidly. And this is where Rupert went from a fishing port of not known by anybody to becoming a place where we do business for both bulk and container.
I think the future of CN, though, is really diverse. So at this point, we really want to leverage technology to reduce -- make our railroads safer as you saw in progress we've done so far. And we want to use technology to make the railroad lower operating costs. We also want to use the technology to improve our customers' relationship, make the business more sticky and attract more freight. And that's what the agreement with Google is all about is to go deeper to the supply chain. Today, some customers want something more than just the raw rail service. They want this thing to be friendly.
And then operating margin will always be key. We're an industry, which is very capital intensive and operating ratio is very key. We're very focused on that. You heard a lot about operating ratio in the third quarter and the quarter to date. So I think there's a combination of these different things that says between growth, between good cost, between technology, between making sure that we are relevant to society on ESG emission and also attracting the right talent and keeping the right talent, all these things are part of the CN's long-term strategy.
And on the -- remember, I think the first time I met you, I was handling the chemical and you asked a lot of question about Dow Chemical and whatnot. Well, guess what, 25 years later, there's still huge potential, a lot of potential in Edmonton, Calgary. There's another wave of capital investment, not refinery or oil sand at this time, but they're more about petrochemical plant that will be export. And that's part of the CN's future again is how these landlocked facility like coal mine, like potash mine, like petrochemical mine, like big, vast growing area for -- in the Canadian Prairies, how do they access the world market.
And there's only one good way to do that, it's with rail. And CN has a fantastic network to make that happen with the 3 coasts and especially Rupert and Vancouver. So I think there's a lot out there for CN to be successful. I'm actually the biggest shareholder of CN as on the management team, and I intend to remain a shareholder, and I'm voting strong for the team and for Tracy. Thank you for the question, Tom.
