The St. Lawrence - Great Lakes region is the world's 3rd largest economy, and is of vital importance to North American trade. The polycrisis we have just been through (health, geopolitical and economic crises), coupled with the incidents that can occur on transport corridors, have highlighted the need to strengthen our global supply chains. Supply chain issues have also become an important component of the inflation rate.

The trade and freight transport sectors are already undergoing changes in logistics strategy (the "just in time" has given way to the "just in case"), workforce and digital transformation. 

Faced with all these challenges, several questions arise: 

• Should we tighten our supply chains?
• Should we modify our logistics strategies to be more resilient?
• How can the sector adjust to meet these challenges?
