Toronto's fancy new green bins might not be as raccoon-proof as they've been advertised. Photos posted to Twitter show the tops of the city-issued organic waste bins chewed straight through by pesky urban wildlife shortly after delivery to residents in Scarborough.

The user who posted the photos claims that the new bins use thinner plastic than the prior version, which makes them susceptible to persistent pests looking for a food supply. Should this prove a trend, it would be quite embarrassing for the city, who awarded a $31 million contract to a California firm to redesign the green bin to be more raccoon-proof.

It would also prove a rare occasion when Giorigo Mammoliti was actually right about something. He was highly critical of the proposed new bins when they were debated at City Hall last year.

So far it looks like raccoon 1, city of Toronto 0.
