Bright and white UFO spotted over Winnipeg, Manitoba

On October 20, 2014, for a few moments, a bright UFO hovered in the sky over the city of Winnipeg (province of Manitoba, Canada). It went into a straight line before disappear. What is it?

Witness statement:

A friend and I were outside my condominium walking to my car. In the back parking lot I saw a flash in the sky, not sure if it was a plane. It was not blinking so I decided to take a few pictures, the one I attached turned out best. I sent it to a UFO sighting site and they confirmed that it could indeed be an alien aircraft. It went into a straight line from NW to SW and then disappeared into the night.
