Just saw Foxer's reply - in Ontario blaze in not a matter of popularity, its the law during rifle season. You must have a given amount of square inches on your body visible from all sides and also must wear a blaze orange hat or head covering (blaze camo does not meet the regs). Probably something to do with the population - there is good hunting within a short drive of major population areas like Ottawa so the odds are pretty good that you'll see other hunters if you are hunting on Crown Land and in my view, having the other hunters see you is not a bad idea.
the exception to the blaze law is during Bear season a bear hunter is only required to wear his blaze traversing to and from his stand and is not required to wear it while in the stand

Hunter Orange
The objective of the hunter orange regulation is to maximize
hunter safety without negatively impacting hunting success.
Under this regulation, all licensed hunters, including archery
hunters hunting during the gun season for deer and moose, are
required to wear hunter orange. As well, all black bear hunters
hunting during the black bear season are required to wear hunter
orange except when in a tree stand. (This exception is in place
because, unlike deer and moose, black bears have colour vision.)
Waterfowl hunters, wild turkey hunters and archery hunters in
archery-only areas are exempt from the hunter orange requirement.
