Vertaling van "refining in canada would become profitable pretty quickly " (Engels → Frans) :

If, for example, all we delivered was what Mr. Harper promised, which would be that bitumen would not be exported to Asia, upgrading and refining in Canada would become profitable pretty quickly.
Si, par exemple, nous honorions ce que M. Harper a promis, à savoir que le bitume ne soit pas exporté vers l'Asie, la valorisation et le raffinage au Canada deviendraient assez rapidement rentable et source de profit.
