From what we've observed in Ontario, and a number of regions across the country, I would say that it isn't a priority for municipalities. The development of official language minority communities doesn't enter into their mandate unless the French-speaking minority in the municipality has a significant demographic weight. That's when it becomes part of city council's mandate.
Take the City of Ottawa, for example. It doesn't have the political will or intention to address that issue. The city's position is that its focus is on services, not the integration of immigrants or newcomers.
