It looks like there are a few provincial political party conventions going on.
The Alberta NDP is having theirs October 20-22. Observer Fees: $25 members/ $75 non-members
The BC "Liberals" are having theirs November 2-4. Observer Fees: Good luck trying to find any, though I hear that they are around $500 for Non-Members
The Saskatchewan NDP is having theirs November 17-19. Observer Fees: $25 a day to a maximum of $50 + GST.
Unless I've got something wrong here, it looks like the NDP Conventions have nothing to hide from everybody, while the BC "Liberal" Convention seems to try to do everything to keep the doors shut.
