A blue road stud or cat's eye marks a fire hydrant

These blue reflectors are installed on, or just to the left of the centreline of the roadway. They were first introduced in 2004. They are called retroreflective raised pavement markers or RRPMs. In other countries they are called road studs. 

While you might not notice them while you are driving around, they are useful for vehicles attending a fire because they can quickly locate a source of water.
