Don't know about Canada, but if it runs above the gear, that's an NEC violation. See Article 110:
(1) Indoor. Indoor installations shall comply with 110.26(F)(1)(a) through (d).
(a) Dedicated Electrical Space. The space equal to the width and depth of the equipment and extending from the floor to a height of 1.8 m (6 ft) above the equipment or to the structural ceiling, whichever is lower, shall be dedicated to the electrical installation. No piping, ducts, leak protection apparatus, or other equipment foreign to the electrical installation shall be located in this zone.
