@realcaseyrollins couple Canadian ones I know of relating to Sikh religious objections to dress codes:
Sikhs may not trim their hair, including facial hair, in respect for the natural state of their body as intended by God. In the military, they can legally be ordered to modify their hair for operational need (e.g. to accommodate gas or oxygen masks), but in the absence of such orders, are exempt from the normal regulations concerning hairstyles.
Sikhs must carry a dagger, to maintain readiness to defend the helpless. Schools cannot prohibit the wearing of the dagger, but can require it to be immobilised in its sheath so it cannot be drawn.
