Ms. Brunelle, the short answer to your question is yes, that's true. U.S. law applies, and it would trump any agreement that MDA or any successor corporation would have with the Government of Canada. The regulations from which Professor Stojak was reading are quite explicit in that regard too.
I quote from them, in the opinion you have, just to highlight the provision on point under paragraph 960.10. These are the consolidated federal regulations, part 960, which are promulgated under the legislation we referred to:
The licensee may be required by the Secretary
—and this is the secretary of the NOAA—
to limit data collection and/or distribution by the system as determined to be necessary to meet significant national security or significant foreign policy concerns, or international obligations of the United States.... During such limitations, the licensee shall, on request, provide unenhanced restricted images on a commercial basis exclusively to the U.S. Government....
That's U.S. law. A U.S. company subject to this law has no opportunity to contract out of the statutory obligations that apply to it. It's that simple.
