Crayola has a trademark on the smell of its crayons

Crayola has one of the few registered scent-based trademarks in Canada:

A unique scent of a pungent, aldehydic fragrance combined with the faint scent of a hydrocarbon wax and an earthy clay.

Trademark application 1986544 [1]

In Canada, a trademark can be anything that is used by by a seller to distinguish their goods or services from those of others. The law gives the following examples of things that could be trademarks, and it's not even an exhaustive list!

a word, a personal name, a design, a letter, a numeral, a colour, a figurative element, a three-dimensional shape, a hologram, a moving image, a mode of packaging goods, a sound, a scent, a taste, a texture and the positioning of a sign.

Trademarks Act [2]

Theoretically there could be some hilariously specific trademarks out there — if only someone would think to litigate over them.
