I don't know what Catholic school is like there, but all four of my cousins have gone to Canadian Catholic schools. From what I've heard, they emphasize too much on religious study and not enough on the academics that will actually help you in life. I don't know if you are considering it for the religious aspects, but it's something to note. The latter option, depending on what the actual job is, may be more beneficial, since you are actually getting real life experience.
