so northern ontario where there is no major cities is the best place to see nature, especially during fall/winter but youll be lacking in anything really night life, or food wise for additional fun, its more of a go hike somewhere in the wildnerness and enjoy
you can however find little out posts of nature in city like areas
toronto is more for shopping, night light, unique and upclass as well outings
ottawa is the capitol of canada, youll find alot of parliament, history and architecture , but also a city life with lots of diversity.
Niagra falls is really fun and only 2 hours from toronto, you can find nature is your travel just outside, niarga on the lake is really old but cool lots of neat shops. niargra falls itself is basically one big cool night life scene with lots of fun stuff like ripleys muesum, farris wheels, bowling, lots of lights, like a little town of fun adult/kid zone las vegas without the gambling it also has a lot of wineries
the main issue with ontario visiting is that is LARGE as fuck provenice, youll need to fly or drive to several locations if you plan to travel around it, you wont find a small metro to take you within 1 hour to several towns, except maybe southern ontario where you can ride the metro places within a few hours
but if you stay in southern ontario you can travel to just outside collingwood to go to Georgian bay for blue mountain resort.
if you really wanna go to canada, british columbia, vancover are probably the better areas. but ontario does have its beauty, its just that its soo spread out that its hard to travel it all within a small time frame
