I am planning to go to Ontario for a week in September. I was thinking of staying in Toronto for 3 nights and then maybe heading to Niagara Falls for one night . Is it worth saying a night or would a few hours there be enough? We will be renting a Car for the last 4 days but are flying out from Toronto. We were going to travel around see some of the countryside (and here is my weird question) My boyfriend is very much into his dairy farming, where would be the best place to travel to for this "sightseeing" ?
