Thank you for your question.
If you take a moment to look at the market and what works well for others internationally, you notice something right away. Just as the Internet works using networks, ports that work using networks are better organized in countries where it's allowed and in countries where strategic alliances can be forged based on complementarity, and especially on synergy.
If you were looking to make improvements, I feel that greater flexibility in this regard could certainly help loosen things up and make the Canadian port system more resilient.
