There is now a Facebook group setup for Canadian collectors. Just do a search for "Canadian Insulator Collectors" on Facebook and it should pop up. Please join if Facebook is your preferred method of communicating with other collectors.
I really wish more collectors would use this forum as it's better geared toward insulator discussion, but Facebook seems to be taking over these days. To me, Facebook doesn't have the proper format yet for group discussion but hopefully they improve the 'Groups' feature to have more forum-like features if that makes any sense.
Here's the link to the group:
