I would like to provide an answer to your first question as to whether there is evidence that parents are choosing French immersion rather than French as a first language. We don't have hard data, but we know it does happen for a number of reasons. If there's not a nearby school, parents will be tempted to send their kids to French immersion. If the French language school is located very far away, they're reluctant to have their kids on the bus for a long time. We have kids travelling over an hour to get to school and an hour back, two hours and sometimes more. Those are dedicated parents, who are determined to have their kids enrolled in a French language school, but if you don't have a nearby school, that's playing against your clientele.
