I did this last year and thought it was interesting, so I decided to do it again this year... Anyway, here are a couple graphs and such thrown together to show attendance figures around the league.
I just used the wikipedia figures for capacity (although I changed the Toronto one as it was posted on the forum what capacity would be this year, due to the closing of the upper level). I know BC Place and Commonwealth Stadium are also partially blocked off, so if anyone has the capacity figures for those stadiums I can adjust... Anyway... here's what it looks like so far:
As a comparison, last year as of week 5, the average attendance across the CFL was 28,777.
Yes, the images are a little big... but oh well.
