I’ve been believing this for a very long time but I’ve seen a video made by a French Canadian that proved me wrong
As a matter of fact, when first immigrants arrived in Nova Scotia, most of the French people weren’t even speaking French, but regional dialects.
What happened is that immigrants had to spend long periods of time in big ports of France before taking the boat to the new World and this is how they learned to speak French.
But English was the language mainly used for trades, and local French speakers included a lot of English words in their daily dictionary (which were then exported to France)
Then England took control of Canada and tried to eradicate the French spoken there because they thought it was impure and perverted.
French speakers were pissed, and began to protect the language with tough anti-English rules
Before the moment England took control of the Canada there wasn’t any protective law because there wasn’t a need to.
Protection measures appeared after that
