uOttawa grad here: is there any co-op option at Carleton? It wasn't very popular at uOttawa, to the point that my employers were getting Waterloo grads because they couldn't find anyone local. There's a lot of cool companies in the capital (not just Shopify!), I'd recommend trying to find a position while you're still a student.
While not a 1:1 replacement, you could consider applying to jobs for the summer on your own. I've met a lot of people in California from the University of Toronto who've done so.
