I saw two objects following each other along the exact same flight path over the city. They came in from the SSE and were heading NNW. I couldn't be exact about the height but it is a very clear night and there were a few light altocumulus clouds so I'm guessing that they were anywhere from 7500 feet upward but I can't say for sure because I have no clue as to their actual dimensions.

When the first one appeared I was confused as to wether it was a plane and as it grew closer I thought they might just be balloons but then I relaise that it wasn't light reflecting of the balloons but infact light moving in a circular motion probably around the edges of the craft. There was a light haze around the craft probably caused by the lights refracting in the air around the craft. At times the circular motion changed to an elliptical one as though the craft had changed its angle of attack but it was definitely moving at a unifrom crusing speed with no erratic motion and a continous heading.
Skeptical as I am, after it passed over my buliding and out of view I looked down and a second later saw the second one following just like a replay. I studied it to the best of my visual ability and I am confident that it was not in the shape of any aircraft that I am aware off.
I am not under the influence of anything alcoholic or any kind of drug. I am a logical, sound person with a few hours of flying time under my belt and have always been skeptical of UFO's and am still skeptical of alien life forms investigating our world but I can say for sure that the craft I saw tonight is unidentifiable.
One thing I know for certain is that the Toronto City Centre ATC and the Toronto Pearson ATC should definitely have seen it on radar.
