Shouldn't they? If your building isn't supposed to have advertising on it in the first place, why wouldn't the municipality have the right to remove the advertising? This is not merely a question related to Olympic powers, but if your Pepsi banner is an illegal advertisement, it should come down. (Frankly, not enough of this is done here in Toronto.) Where I'd have a problem with this is if you had a LEGAL advertisement space in the Olympic area and they prohibited you from showing whatever advertisement would be permitted in your space regardless. If Pepsi were willing to pay your normal rate for a billboard that you legally have on your building, the city should not be able to remove it under any circumstances. It's worth noting that cities DO occasionally enforce outdoor advertising regulations and that some folks (e.g., http://illegalsigns.ca/ http://illegalsigns.ca/) think it's a good thing. I happen to agree. EDIT: Added link to the Illegal Signs blog.
