If, for example, in Montreal you were a truck driver driving to an airport, you would require a transport security clearance. Our hope is that, over time, one transport security clearance would suffice, whether you hauled dangerous goods, whether you had to go to an airport, or a railway yard, or into a port, and hopefully, eventually, if we can get reciprocity with the United States, to cross the border.
I hope that answers your question.
