Thank you for the question and for the comments on our performance. We're very grateful for those.
Infrastructure is one of the strategies that we invest in. It's a strategy in which we've invested approximately $16 billion over the years, and we have about $22 billion of current value invested in Canada and around the world in infrastructure. We've invested in a variety of different types of infrastructure from toll roads to pipelines to ports and will look to continue to find opportunities.
One of our challenges is that in order to maintain a reasonable cost structure internally our team can't be too big. We need to keep a relatively small team. That team therefore generally restricts itself to look for quite large investments. That's the way we can keep our costs reasonable. We generally look for investments of over $500 million when we're looking for new investments. We welcome more opportunities to look for those types of investments.
