Hypothetically, if Canada had these jets plus (conventionally armed) nuclear subs we'd be a world class force to be reckoned with. We could threaten the US, that we'd stay out to sea and strike unexpectedly, if they ever took more of BC's coast.

But do we need this? Especially being 99.9% like-minded to our brave neighbour to south? It's not worth it, instead we'll help them stay on top and they'll help us with any ordeals, including the assertion that the North-West passage is Canadian. (against any hypothetical opponents, like the Ruskies) And we'll get high tech jobs for our kids.
These jets will help us in many ways.
