Hey Mel. I'd recommend getting in touch with Clifford Carnicom.

Researching Chemtrails has been a passion of his, and checking out his site and other linked sites from his will give you a host of questions for him.
The Chemtrailing has been the heaviest I ever recall seeing it here, a bit west of Toronto.
I took some pictures today I'll try to upload.
