When I speak out, am I still bound by professional secrecy or by employer loyalty obligations?

Corps

When you make a disclosure or cooperate in an audit or investigation stemming from the disclosure, you are allowed to reveal any information you would not otherwise be authorized to give out for reasons of confidentiality and loyalty.

You are protected under the Act respecting protection against reprisals related to the disclosure of wrongdoings.

See the How am I protected? section to know more about protection against reprisal.
