You in fact do qualify for English public schooling.Does this apply to study permit holders too? If I accept an offer from Bishop's Uni my kids (14,12,6) will be joining me in Quebec. Will they be only able to go to French public schools as well (unless we opt for private schooling)?

It would be best for you to contact the English Montreal School Board directly to get help in applying for a temporary certificate of eligibility. Keep in mind that your certificate is only valid for the duration of your study visa and your children will be forced to switch to French school if you apply for permanent residency in the future. There is a well known loophole for immigrants to get their children into the public English school system (after several years of private school) but you need to be a Canadian citizen to take advantage of them. The certificate you will receive is only temporary and is different from the permanent certificate granted to Canadian citizens who qualify and which can be passed down from generation to generation.
