Moncton NB is the most bilingual city in Canada. 125,000 people-  67 % English and 33 % French of which a total of 50 % are bilingual--higher than Montreal I  expect. Montreal is slipping in terms of bilingualism as its economic position sadly  deteriorates further. I remember Montreal in 1967 was a thriving city and Canada's financial centre -it is down to third now.
