The presence of the other cultural groups in Canada is something for which all Canadians should be thankful. Their members must always enjoy the right -- a basic human one -- to safeguard their languages and cultures. The exercise of this right requires an extra effort on their part, for which their fellow Canadians owe them a debt of gratitude. Their presence facilitates communication between Canada and the rest of the world. Their cultural values find expression not only in popular traditions but also in arts and letters. In our opinion, those values are far more than ethnic differences; we consider them an integral part of the national wealth.
