Those are "Pacmin" models and are airline display models purchased on e-bay or gifts. I really don't have the time to build my own, one day maybe?
I have had a few dealings with Peel Regional and if you are polite and explain what you are doing they usual just leave you alone. There a few spots that are not the best place to be taking pictures as they seem to have come to the realization that "spotters" or "shooters" will always be around. There is also an Airport Watch Program in effect at Toronto YYZ.
Here's a link:

This isn't a "get out of jail free" program but gives some credibility to people who prefer to spend their spare time at the airport watching aircraft. I belong to the Watch Program and have come to meet more fellow spotters at YYZ.
If anyone elso monitors ACARS in the Toronto please let me know, looking for more local logs to add to the other ones in the area. It is a great way to tie-up overflights and aircraft landing/departing at YYZ.
Thanks for your comments!
