Can TD visa holder work as a volunteer?

My wife's status is TD. She is looking for pharmacist intern job to get some local experiences. Can she work as a volunteer without pay?

Thanks

No, She can only volunteer for (a) organizations that typically use volunteers and (b) in positions that are typically unpaid.

Pharmacy intern is neither.
