One of my favourite places to go, although more then the 2 hours you are looking at. Bob and Peg are terrific hosts. Down fall is you are a bit of a drive to anything for dinner. Sudbury gives you some choices but you cannot beat "The Bus" in Killarney for fish and chips.
Whispering Pines On The Bay
Here's my report from a few years ago. (Woodgrange B&B doesn't have a listing anymore, maybe just closed for the winter )

Of course you can search BBCanada . Been using that site for years and must have stayed in 30+ B&B's over the years, never had a bad experience.
Another one that is a bit closer to your 2 hour range is Inks Spot B&B in Huntsville.
