The primary role of Lower St. Lawrence pilots is to ensure safe navigation, respecting not only the safety of those who live along the river and use it, but also environmental and economic safety.

Every year a considerable quantity and diversity of toxic products are transported on ships using the St. Lawrence River.
Any stoppage of traffic on the St. Lawrence as a result of an accident or a stranding would automatically entail major economic losses.
