Thank you very much for your question.
I can say that we share the concern that you've expressed in terms of implementation of any new requirements to cross the border. We also share a concern with what's been termed as a thickening of the border. This is partly one of the reasons we are promoting the IBET model, which is actually looking at a balanced, layered approach.
In terms of enhanced or additional travel documents, the risk always exists that if the passports can be counterfeited, it's reasonable to think that any other kind of document has that potential as well.
In terms of our views specifically on what happens at the port of entry and what Canadian citizens are going to be required to produce, this is a question, I believe, that would be better directed to CBSA. Unfortunately, in Canada there are two agencies that are responsible for securing the border.
