Effects on navigation
268 In addition to any other factor that it considers appropriate, the Commission must take into account the effects that its decision might have on navigation, including safety of navigation, when deciding whether to issue a certificate or permit, make an order, give a direction or grant a leave, approval or exemption in respect of an international power line, or an interprovincial power line in respect of which an order made under section 261 is in force, that passes in, on, over, under, through or across a navigable water.
