Might be a bit far for you. But I pay $25 month just outside Lindsay. I have a 24' old truck box I use a storage for toys. It is a secure compound, (fully fenced, with security cameras which you can view remotely). Normally minimal if any access during winter, (but if your using for track bike not using it during winter anyway).
Each "tenant" has their own key so 24/7 access.
It is called OPS storage and flea market
