That wouldn't work, unless they move their whole engineering building outside of the US (I don't think Canada would do, because they have similar laws, and treaties with the US).
The claim has been made that OpenBSD, by virtue of its development being based in Canada, doesn't have the crypto export restrictions imposed by the spooks here in the US; see
http://www.openbsd.org/crypto.html
although that page links to
http://insight.mcmaster.ca/org/efc/pages/doc/crypto-export.html
which discusses some possible complications with, among other things, the US laws.
