Did not see the object at the time, noticed it in a picture when reviewing at home. At first I wrote it off at the sun, however it is in front of dark storm clouds and there is no yellow-orange glow anywhere else in the clouds and when you look closely you can see a arcing trail to the right of the object. Picture taken with a Sony DSLR A390 with a 75-300 mm lens. We were on the locks over the rapids going from Ontario to Quebec and the camera was pointed to the SE.
