^ I left montreal in 2009 and came back in 2012, and it felt like the number of French people in the streets had doubled in that time. Many of them are likely here temporarily (students etc) but experience shows they are more likely to stay or come back.
CIC reports that the annual inflow of permanent residents from France has pretty much doubled since the early 2000s, going from roughly 4000 to 8000 a year. Likely most of them coming to Quebec, and specifically Montreal.
