Hi all Canada experts! Me and my SO will have a roughly 24 hour layover in Toronto in May (landing around 4PM, leaving next day at around 5PM), before heading to LAX. I have already booked us into the Sheraton Centre downtown. Having never been to the city before, I am wondering how to maximize our stay. What should we not miss? Is it wise to rent a car, or are web etter off using public transportation? It also struck me that the Niagara Falls are also pretty close, is that something you recommend? I suppose we could get up really early in the morning and drive out to them, or is it to risky considering our 5PM departure for LAX?

Thanks in advance for all suggestions!
