On Wednesday, secondary students from the Toronto District School Board were taken on a field trip to the Grassy Narrows River Run, near Kenora, Ont. The event was communicated to parents as an educational opportunity for the students to learn about the issue of mercury contamination affecting the First Nation. The permission slip sent home stated that, “while at the event, students will not be participating in the rally itself; instead, they will observe and learn from the presentations and discussions.”
