Hi,
from what I've seen and heard, the Canadian side is by far the more interesting. We have a much better view of the falls.

And Clifton Hill is where you'll probably spend a good amount of your time given all the attractions it has.

But if you search around, there may be a tonne of wineries open too.

There's also a zoo nearby, but at this time of the year it's probably closed.

Lastly, (again if it was just a little later in the season) you'd have Marineland attractions and rides to visit too.

Good luck and have fun!
