Yes, the rivers are great. Lower and Upper Niagara river are great for fishing all year round!
I still wonder if salmon swimming upstream in Lower Niagara try to go up the Niagara falls
that would be an awesome footage to have.
When you go out fishing here, you really need to take all sorts of baits and tackle with you, because you could get tired of one specie and could easily switch to another. I've been only targeting Salmon and Steelhead so far.
If any of you guys planning a trip to Toronto, make sure to give yourself extra few days for fishing. You gonna love it. However, make sure you check reports and websites to know where to go to and what to target ahead of time. That way your trip will be worth it.
