Lights over Vancouver

On May 16th I took my dog outside for bathroom at about 11:00pm. As soon as we got outside I looked up and saw a long line of bright white lights crossing the sky. The line of lights went as far north as I could see, (about half the night sky before the horizon was blocked by an apartment building) and as they moved over head they would just disappear one at a time in the same exact spot. The lights were moving relatively slow and were in a perfectly straight uniformed line, all the same distance from one another. I tried to film it with my IPhone 8, but nothing showed up so I ran inside, told my girlfriend to come out and grabbed her iPhone 11. I went back outside and tried to film with her phone, but it still didn’t show up so  I went back inside and Convinced my girlfriend to come out and she also saw the line of lights. About 10 or 15 seconds after she came out another much much larger bright light appeared and started to move across the sky at the same ! slow speed in a different direction. After about a minute and a half from when she came out the seemingly endless line of lights came to an end as we saw the last one pass over head and disappear. At that point my girlfriend went inside, but I stayed and watched the larger bright light until it went out of view over the horizon. It was literally just that, a large bright circular  light, nothing was blinking or had any color at all, and I didn’t even think to film it because I had already given up on filming before it appeared. In total I watched the lights for about 5 to 7 minutes and they were already in full swing when I first saw them. Also while I was filming the first time I watched a small farm plane fly right by the line of lights. I guarantee he got a great view of them, he may have even  been able to see where they were originating from idk. Here’s the thing Where I live is a very densely populated area near an airport so I’m amazed I couldn’t find a report from w! here I live that nigh (which is why I’m reporting this) so if ! anyone g ot a different  view please report, especially if anyone got it on film, that would be so cool!
