Only if you plan to ship it out of the country.
In order to export the fish out of Canada (meaning overseas, as the USA/Mexico are illegal), you would have to either use the bulk CITES import cert used in the importation process or else apply for a whole new CITES permit for the purpose of re-export. Years ago when the farms were short on brooders I heard that they were willing to pay good money to get large brooder fish shipped to them. Still, I have never heard of a fish legally leaving Canada.
