Respectfully, I did provide you a list of all the measures that are being undertaken. We've also provided a comprehensive list to Transport Canada that outlines all the different vehicle security systems that have been put in place. While I can't give you a number, we have provided comprehensive information to the federal government on all the measures that are in place.
I also want to be clear that we can't make all this information public because that would be handing it over to the very groups using this so that they can find ways around these systems, so there is an element of this that needs to be kept secure.
