I'm going to use my colleague's analogy of team Canada. It is a team sport, so the investment is not only, for example, in our locks and bridges infrastructure. It has to be through multiple actors working as a system. I'll name a few.
For containers, we need customs clearing with CBSA. For navigation along the seaway, we need icebreaking capabilities for winter operation with the pilotage service. There are other services that are provided to the vessels. Terminals need to have the proper stevedoring and all other services.
