UFO Sighting in Toronto, Ontario on June 6th 2015 – two glowing lights in the sky that changed color and shape as they flew

At 9:45 pm EST my husband was out on our deck when he saw two bright lights suddenly appear in the sky over our house. These lights just appeared from nowhere as if someone had switched them on. He called me outside and I saw two bright lights, quite large, pulsating red, orange, yellow and green (main colors were red and orange) travelling soundlessly across the sky in a northerly direction. after about 30 seconds, the lights went out and the objects turned an opaque white color and were disc shaped. As they moved across the horizon one appeared to become somewhat distorted, more elongated as if it was changing shape. We lost sight of it as it passed over some trees and out of sight. Very strange and like nothing we've seen before.
