RailWatch Canada is a public infrastructure intelligence platform tracking dangerous goods movement on Canada's freight rail network. It is a property of Critical TO, the Toronto infrastructure intelligence publication.
The platform exists because of a transparency gap: under Canada's Transportation of Dangerous Goods Act, freight railroads are only required to notify provincial fusion centres of dangerous goods routing — not the communities through which those trains pass. A resident A community observer watching sodium hypochlorite cars roll through a CN station at midnight has no legitimate path to know where those cars are going, who shipped them, or why.
RailWatch does not claim to solve that gap. It documents it, contextualizes it, and builds the community observation infrastructure that will become meaningful as transparency improves.
