For those of use Canadians who are used the the ups and downs of our dollar, this has always worked both ways.
For example:
Fairmont certificates were always issued in USD even though Fairmont was based in Canada.
There was a somewhat what brief period when the CAD was higher than the USD and we took our lumps with the value of the certificates dropped. No harm, no foul.
There are posters on this thread that have no clue as to what they are claiming and/or rambling on about.
