ufo details report: My brother and I were driving on hwy 403 in Ontario,Canada when we observed many car pulled over to the side looking at something.We decided to pull over and see what the fuss was about.When we pulled over we viewed a round shaped disk hovering about 800 feet in the sky above a large field not moving.We and everyone there was in ahhh and couldn't explain what we were seeing.It was silverish and black and just stayed right in the same position.After 5 min.,we decided to leave with the object still there.Can never forget this and wish we would have stayed to see what happened.It was between Woodstock and Brantford around the Brant area on the 403 hwy.It was not to far off the highway and not very high up in the air,very visible.
