Of course there are. Most people I know speak English and a little French, or speak French and a little English. I know quite a few people who are perfectly fluent in either language. I'm not fluent in French- I have trouble writing it, and sometimes mangle verb conjugations- but I understand fine if someone is speaking French (as long as they aren't speed-talkers), and I can read it even better.
It's hard not to pick it up, since French is a mandatory class up to Grade 9 where I live, and schools very much push it even in the later grades. There are also more job opportunities if you are bilingual- many government, service and tourism positions require at least some fluency in both French and English.
Oh, well. C'est la vie!
