There's a range, and they would include those transit examples you mentioned. I think we see this in a number of cities. Four of the ten most congested cities in North America are in Canada. So I think we need more of that in Montreal, Toronto, Calgary, Vancouver. There would definitely be a transit piece to it.
The second thing is around the gateways. We think agri-food is a big opportunity for Canada. We should be a global champion, but we don't have the capacity in the rail and in the ports to be able to deal with that. We haven't done the analysis on it, but I'm looking at the Emerson report, which we considered quite closely, and we think that there's infrastructure there and that there are investors who would love to invest in a port or in rail hopper cars. People would be interested in investing in any part of the infrastructure that's there. In that case, businesses in a sense would be paying the fee the investors would get.
We think electricity grids are another possibility. We're fortunate to have one of the biggest sources of green energy, but how do we transport that energy to different parts of the country, or to the U.S.? We think there's an opportunity there. There's a pretty standard fee-based approach we think we could build into that, which investors would see. Then there's the whole 5G broadband area, which we think is going to require investment across the country. This is one we believe can be structured. This has been happening in other countries, like India, where they're getting people to help pay for the infrastructure that's being laid down.
I don't know if that gives you the detail, but our sense is that ideas should also be coming from the municipalities and the provinces. This isn't a case of the federal government telling us what they want to do. The idea is that there should be some screening or criteria. For example, the project should be over $100 million. Institutional investors aren't really interested in investing in anything less than that, and we think it's necessary in developing that pipeline of the projects you're mentioning. I don't know if I'm being specific or not.
