Cycling in Waterloo Region

[Pheidippides]

Actually the HTA does require lights before dawn and dusk, but only on the front and a minimum of red reflectors on the back:

Cyclists must have proper lights, reflective materials and reflectors on their bicycles (and that includes e-bikes) and motor-assisted bicycle (mopeds). HTA s62(17) says:
When on a highway at any time from one-half hour before sunset to one-half hour after sunrise and at any other time when, due to insufficient light or unfavourable atmospheric conditions, persons and vehicles on the highway are not clearly discernible at a distance of 150 metres or less, every motor-assisted bicycle and bicycle (other than a unicycle) shall carry a lighted lamp displaying a white or amber light on its front and a lighted lamp displaying a red light or a reflector on its rear, and in addition white reflective material shall be placed on its front forks, and red reflective material covering a surface of not less than 250 millimetres in length and 25 millimetres in width shall be placed on its rear.
