Here's how it works: If a cemetery is permitted, the neighbourhood will regularly become over crowded by mourners from outside the community. Illegal parking, littering, washrooms, noise and disrespect for the surrounding properties become sources of tensions. The locals will be called Islamophobes  if  they object to how their lives are being upset.  Property values will drop and the only buyers will be Muslims. In 10 years the entire neighbourhood will be Muslim.  Old homes are torn down and 10 bedroom 5000 sq ft homes are constructed. Schools will have Muslim Prayers.  Halal foods will be ubiquitous in the stores.  An application for a  mosque will be submitted, which will attract more people to move there. Restaurants, shopping and service businesses that cater to the new clientele will open. 
However, despite the buzz of economic activity,  unemployment among the local Quebecois will go up. Even public sector jobs will be out of reach.. It's what happened all over Europe.
