C-26, r. 10 - Regulation of the Professions Tribunal

Full text
37. No attorney may address the Tribunal unless he or she is wearing a gown, white collar and bands and dark clothing.
The same rule, except for the white collar and bands, applies to articling students.
Before a single judge, the wearing of a gown is not required. All attire, however, must be simple and unadorned.
Any other person who appears before the Tribunal must be suitably dressed.
