Yes, you are entirely correct.
I think you are talking about the case brought by Ballantyne and Davidson. In its decision, the United Nations Human Rights Committee clearly said that the relevant entity in international law is the sovereign country, that is, Canada.
Anglophones everywhere in Canada, including in Quebec, form a majority and are therefore not considered to be a minority that enjoys special rights as such.
By considering English Quebeckers as a minority in need of special protection when, in fact, they are part of the Canada-wide linguistic majority, yes, we are in conflict with international law.
