giant bright sphere traveling east to west in ontario.

at about 7:30pm on halloween night , i was taking my two small children around the block for halloween. we had reached the corner of our street , when i noticed something out of the corner of my right eye. i was standing facing north at the moment. i looked up to see a bright whitish almost chrome sphere , traveling east to west , at first i thought it was a meteor. but after i focused on it i realized it was neither a plane or a meteorite.the speed at which it traveled was slower than a meteor , but much faster than a plane , it made no sound , and kept a constant altitude until it disappeared into the tree line in the distance. at one point it seemed to release a spark , but had no tail whatsoever. after the object had passed i realized two of my neighbors were standing right next to me , and had witnessed the object with me. i am a thirty five year old male , and have seen numerous meteorite showers , planes and orbiting satelites passing overhead.and i am certain this was no man made object. this was an experience i think of almost daily since it happen!
