Absolutely. At ports like Montreal, where there are dangerous goods that could potentially affect neighbouring dwellings or things like that, there are risk assessments done through Natural Resources Canada. They do what they call explosive limit risk assessments to determine the proximity of dwellings and populated areas with respect to the port and what dangerous goods could be stowed and where they're stowed. They're often stowed in particular areas in a port, and in some ports in fact certain dangerous goods are not even permitted to be brought in.
