Line of Lights in the early morning sky

At 6:30am on December 5, 2019 in High River, Alberta, I was outside with my dog and looked up at the stars, as I often do.  I noticed a series of white lights tracking from the north towards the south east.  There were several lights all in a row, forming a line of lights in single file (not in formation).  The line continued to the south east right out of my view.  I cannot tell you how many lights there were exactly but I did count over 30.  There was no sound and no color or flashing.
The lights just kept coming over the house were moving quickly and at a high elevation.  I did not take any video or photographic images as I was so awestruck by the whole event.
There was a plane that also flew over the house tracking north to south a much lower elevation at the same time, I expect the piolet would have also seen the lights also.  The plane did not appear to be involved (ie: following the event).  This was clearly a plane as I could hear the engine and see the flashing signal lights of a small aircraft.
