Add Comment Question: Is an employer allowed to ask for salary history in Ontario? As a requirement for interviewing with a company, I was asked to provide my salary history for the past 10 years and I'd have to consent to a verification of those $ numbers (to make sure they're not made up) upon acceptance of an offer. Is this not prohibited per the Pay Transparency Act? Answer: Yes, as per the Pay Transparency Act, Ontario employers are prohibited about asking candidates about past compensation.
