The single light standard to stop the north bound traffic on High Park Ave at Dundas St West

The configuration of the new light standards  comprising the new installation  of the traffic lights at High Park Ave and Dundas St West appears to be unusual to the writer of this post. The setup appears to have just one stop light standard to stop the north bound traffic on High Park Ave at Dundas St West. Is this an unusual design or not? anyone have an idea?
