No, because this is an internal negotiation—if I understand you correctly—among the members of the alliance. Once it's finished, it's finished. Canada is just an observer. If Canada wants to get into the other category at the level of a full member, it will start negotiations. There is at least a year to negotiate some sensitive points, and then there is going to be a decision of the Council of Ministers of the foreign alliance to decide if Canada or another country has fulfilled the conditions to get in.
