124. (1) No tolls or money shall be charged or collected by the company as a common carrier unless the by-law fixing the rates of such tolls is in force under subsection 6 of section 123 and unless the requirements of this act are complied with.
(2) Such tolls may be either for the whole or for any particular portions of the railway; but all such tolls shall always, under substantially similar circumstances and conditions, be charged equally to all persons, and at the same rate, whether by mass, kilometre or otherwise, in respect of all traffic of the same description and carried in or upon a like kind of cars, passing over the same portion of the line of railway; and no reduction or advance in any such tolls shall be made, either directly or indirectly, in favour of or against any particular person or company travelling upon or using the railway.
(3) The tolls for larger quantities, greater numbers, or longer distances may be proportionately less than the tolls for smaller quantities or numbers or shorter distances, if such tolls are under substantially similar circumstances charged equally to all persons.
