You don't leave yourself a lot of time to see a really scenic chunk of Ontario - on the other hand you are going through at a great time of year but check the Ontario Parks website for operating dates.
The route you are taking is one that we take pretty much every year from Thunder Bay area to visit family in the Niagara area.
I've listed our favourite parks.
I'd also ditto the suggestion to take the ferry from Manitoulin to Tobermory - it is a bit pricey - but if this is your one and only trip to Ontario then you are choosing between a straight-forward non-eventful drive from Sault Ste. Marie to Niagara via Sudbury against the opportunity to enjoy Lake Huron up close and personal and spend time viewing the incredible human and natural history of the Bruce Peninsula - no comparison in my view.
The one significant exception to going around Lake Huron via Sudbury is Killarney Provincial Park. It is a stunningly beautiful park that is well worth a visit if you do go via Sudbury - but - having said that - my caution for you has to do with the size of your rig in your avatar - Killarney is not big rig friendly - check and reserve ahead of time to make sure you can get a campsite that will accommodate you.
