Yes, absolutely. There are tens of thousands of trucks that cross the border between our two countries every single day. There are hundreds of flights that cross the border. There are many ships, and this speaks to a lot of traffic on the Great Lakes from Canada to some of the eight states that border the Great Lakes. It is in our interest to harmonize to the maximum extent possible so that in essence when any mode of transportation crosses the border into the United States, or in the other direction, they're not faced with a whole set of different rules with respect to safety or other issues. Harmonization has been a priority between our two countries, and I'm glad to say it works pretty darn well. We're not totally identical but we try to make it as seamless as possible.
