Come the middle of summer in Toronto, bike parking is at its toughest to find. Not only are more people riding, but various construction projects tend to wipe-out bike posts within their vicinity.

A standard city of Toronto post and ring secures just two bikes. More fit if you double park with a friend, but space is generally limited in high-demand areas unless there's a rack or another suitable vertical object on the sidewalk. (Avoid anything narrower than your lock at the top, people.)

As someone happy to use a bike for daily transportation, I find there are plenty of places in the city where legal parking is next to impossible within reasonable distance of my destination. The Annex near Honest Ed's springs immediately to mind when I think of crowded locks, though Queen West is also pretty rough, too. Post roadwork on Dundas West, the bike posts have yet to re-materialize. On the flip side, the locks near my home in the east end are almost always available.

In a post published earlier today, Cycle Toronto has identified the greatest need for bike parking in Ward 19 (Trinity-Spadina). Condos along the Lakeshore, areas of Dundas West and King West are also particularly bad, they say, with many riders turning to trees, gas meters and other street furniture for security.

The City of Toronto's plan to install just 500 new post and rings instead of the usual 1,000 this year probably won't help matters, either.

So whether it's overcrowding, fear of having your bike pinched by some recidivist, or simply not enough ring and posts, we're asking for the worst places to park a bicycle in Toronto. Here are some of your responses from Twitter. Add more suggestions in the comment section.
