8.8 the requirements of sections 58 and 68 of Bill 178 are said to be deliberately limited to the sphere of external public and commercial advertising, because it is there the symbolic value of the language as a means of collective identification is strongest and contributes most to preserving the cultural identify of French speakers: "the linguistic image communicated by advertising is an important factor that contributes to shaping habits and behavior which perpetuate or influence the use of a language." Quebec concludes on this point that Bill 178 strikes a delicate balance between two linguistic communities, one of which is in a dominant demographic position both nationally and on the continent as a whole. This aim is said to be reasonable and compatible with article 26 of the Covenant.
