CHML has a post comparing beer prices across the CFL. They're surprisingly close. Unsurprisingly, like real estate, BC has the highest prices. Weirdly Hamilton has slightly higher prices than Toronto. I seem to remember big beers in Dead Ted's Dome (TM) being higher than Ivor Wynne, but that may have been premium beers. Do the Argos even get money from beer sales? I seem to recall no, but who knows.
Also if you look closely, CHML can't do math.
