4 bluish-white lights flying in fomation at very high altitude

I went out to my backyard to move the sprinklers to a new position before bed. The sky was perfectly clear and the typical visable stars were crystal clear. As I was returning back to the house, I noticed a moving light in the upper left portion of the sky. As I observed closer, I realized the light was actually four distinct lights not one. Three of the lights were in a triangular pattern and one light was off directly off to the right. They were moving south-west across the sky. The altitude was very high. I intially thought the lights were a single satillite. I have seen numerous satillites over the years and these lights looked nothing like any satillite I have ever seen. The altitude seemed right but the speed seemed faster than a satillite. I realized that these lights were not multiple satillites travelling together or a commercial airlliner. The lights were bluish-white and did not blink. The lights stayed almost equal distances apart without any variations in formation. The lights were definetley seperate entities as i could see the night sky between them. They made no sound. I was able to observe the lights for approxiamatley 6 seconds before they faded from view. I couldn't see any high altitude clouds but figured that may possibly have been the reason I lost view of them. I was in trying to associate the lights to all my past experience with aircraft or satellites to make sense of what I saw. I have never seen anything like these lights before. I'm still mystfied. I don't drink or smoke (anything). I was well rested and not under any stress. I cannot expain what I saw. I find it hard to believe that in the highly populated area of North Burnaby, BC. that I was the only one to witness this.
