Reponse courte en francais: plus ou moins.

Long answer in English:

If you are going to use a clumsy translating program, might as well answer you in English so that you fully understand.

English signs (mostly) on the island of Montreal, French in the rest of the province were the norm. Montreal has always been problematic in Quebec since it has long been a bilingual city. This fact has not changed since your photo from the 1920's was taken.

I'm pretty sure road signs followed the same pattern. It would explain some of the loan words in Quebec French and the battles over road signs that happened later on.

But there has been a national awakening in Quebec 50 years ago or so to reverse this trend in Montreal. Some of it has been coercive (bill 101), but people and businesses now expect French to be the main language (mostly).

The English-speaking minority used to be bigger and stronger in Montreal, but there remains pockets of resistance and legal challenges to language laws are still common. Another interesting factor is while a large chunk of English speakers left Montreal (and Quebec), French speakers are leaving the city as well (for the surburbs, essentially the same phenomenon as urban sprawl in the US) and constant immigration fills the gap left in the city. The integration of these new immigrants and the language(s) they choose to speak is a hot issue lately.

P.S. You are opening a can of worms with this topic (subject and language used) and it's possible it will entice some of the more extreme forum members to post their drivel. Just ignore them.

Assez particulier, dernièrement je faisais une petite recherche histoire de faire certaines comparaisons de protection linguistique. Justement de l'autre côté de la frontière j'ai compté une trentaine d'états qui ont adopté une législation faisant de l'anglais la langue officielle de l'état. Voici une petite image des états qui ont légiféré:

Bleu: Anglais langue officielle
Rouge barré: processus législatif en cours
Rouge: aucune législation

Devinez le premier état à adopter une telle loi ???
