From the flyer text:
"When travelers consider the “inconvenience” of delayed trains, or blocked highways and bridges, contrast your temporary inconvenience with the permanent and deeply entrenched theft of land from native communities, and the adverse social conditions that hundreds of years of genocide have produced.

We are here today to put CN in Montreal on notice that protests and disruptions by non-native allies -- who stand in solidarity with the actions of native protesters across Canada – will escalate if CN does not cease and desist their racist lawsuit immediately."
