Can't think of too many canadian seed sites thanks to the curent polital climate in this country but in my experiance you have nothing to worry about ordering from the Uk or other European companies, Ihave ardered from several and never had a problem, all told must have made ten or more orderes and the seds have always arrived with no problems. On the other hand Nirvanas seeds though cheap are a waste of time in my opinion.
