I posted this over on the CFL board and thought it was worth posting here too.
Just finished ordering my tickets to the EDF on Ticketmaster at THF and thought the prices were quite reasonable. So I decided to see how they compared to all the prices for the other three play-off games and here is what I came up from Ticketmaster. Montreal is pricey - and they have a lot to sell in the next 6 days too. (This does not include pricing for Club Seats or Suites)
EDSF in Montreal ($53 - $150)
WDSF in Edmonton ($47 - $96)
EDF in Hamilton ($47 - $112)
WDF in Calgary ($38 - $115)
