Hey there I'm in Toronto sorry I didnt see this ahead of time but St. Catherines is a bit far from Toronto, were you looking to stay somewhere close to St. Catherines in Niagara Falls or were you looking to stay in Toronto? Niagara-on-the-lake is nice if you like the artsy sort of vibe, Niagara Falls is fun if you want to feel like a kid again. Not sure when you're travel date is but if you have any questions let me know
