As of 10 a.m. Monday the lights on Royal Rd and Saskatchewan Avenue are flashing. Drivers are reminded when stop lights are not working that they are to treat the intersection as a four-way stop. Flashing red lights require a full stop and motorists should only proceed when it is safe to do so. Flashing yellow lights require drivers to slow down and only enter an intersection if it is safe to do so.

There is no information available as to when the lights may be back to normal.
