Does your startup absolutely require that you be in Toronto? Why not do both? Take the opportunity of the exchange and start working on your startup on the side (and be ready to get into it in full force when the exchange is finished).

I started a company when I was 18 and was traveling the world before I turned 21. I still travel now whenever I feel like, and it has not negatively impacted me in business. In fact, I think it has had a very positive effect as I've learned countless things about people and global markets.

Happy to discuss more over a call if you'd like.
