Chemtrailing aircraft over Vancouver, Canada.

I've been having a look at the aircraft activity around the Vancouver area in Canada using flightradar24.com and  saw a lot of chemtrailer aircraft flying their spraying patterns. The patterns show that individual aircraft fly back and forth over the same area for quite a few hours. They also  criss cross the skies to make sure the aluminium and barium etc covers the sky completely. If you click on an aircraft then you should see their flight number and destination etc. This info is usually blocked on the chemtrailing aircraft or the aircraft won't show up at all on the flightradar24 website ( despite you seeing the aircraft flying over your house with your own eyes ).
We rarely get to see the chemtailing patterns in the UK sector as most of the chemtrailing aircraft switch off their transponders making them invisible to flightradar24.com.
Here are some of the screen shots that I took....
