Thank you very much, Madam Chair, and thanks to the witnesses for being here today.

Mr. Casey, you spoke about host conditions, and with regard to Canada you mentioned that we're more in a pull mode than a push mode. I wonder if you could define that a little more for the committee. How do we get from a pull to a push?
