I live in Calgary and they end up here fairly often, but a couple summers ago I took a road trip across Vancouver Island and they were all over the place. I would see planes just going back and forth across the sky and none of the trails would disappear, they would just spread out and stay for hours.

So they are disperse chemicals in a trail that doesn't disperse for hours and hours?
That or atmospheric conditions were such that they would just stay longer becoming basically man made clouds.
Contrails are as old as high altitude flight.....
So either they are 'really' chemicals and have 10000's of people hiding it for 60 years....
Or the crazy websites are wrong and the scientists are right.
