UFO Sighting in Ottawa, Ontario on 2017-04-28 17:45:00 - Hovering bright cylinder

While driving home from work, i spotted a very bright shining white light hovering above the tree line. i thought it was a small plane at first, although it did not move like a plane, but hovered in one place with slight sideway wobbles. another plane with a contrail could be seen in the horizon at a much higher altitude. it was a warm sunny afternoon with few, if any, clouds, and the sun could have been reflecting on the surface of the craft, alternatively the craft was emitting the bright light. the craft had the appearance of a silver/chrome cylinder, no other details could be outlined. i continued to watch the object for 10-20 seconds as i was driving in the direction towards it, but had to keep an eye on the road as well. i met a couple of cars in the opposing lane, and eventually as the road crossed through the tree area i briefly lost sight of the object. however rediscovered it within 1-2 seconds at a much higher altitude, much smaller, and no longer shining/reflecting bright light, only metallic looking. unlike an airplane the ascension would have occurred very fast while the cylinder remained parallel to the ground. 2-3 seconds later i could no longer see the object. the duration of the entire sighting was probably less than one minute.
