Northern Ontario is a fantastic drive, particularly the Superior shore. One of my favourite places on it is the Terry Fox Memorial, commemorating the young Canadian who attempted to run across Canada circa 1980 with one artificial leg, to raise funds for cancer research.
The memorial, located where Terry ended his attempt due to recurrance of the cancer that killed him a year later, is on an incredibly beautiful overlook of Superior, about an hour southeast of THunder Bay. And, very sensibly, it has the best washrooms on the entire Trans-Canada Highway. Don't miss it!
