What mechanism is NOT used by Ontario to protect consumers?

The correct answer is travel industry insurance, as it is not a specific mechanism employed by Ontario to protect consumers in the travel sector. Instead, the other options represent established methods designed to enhance consumer protection.

The registration system ensures that travel agencies and service providers are credible and meet specific regulatory requirements before operating. This transparency helps consumers make informed choices.

A compensation fund is a critical protective measure that provides financial restitution to consumers in the event that a registered travel agency fails, safeguarding their investments in travel services.

Truth in advertising is a policy that requires travel providers to present their services accurately and refrain from misleading claims. This is vital for maintaining consumer trust and ensuring that customers can rely on the information provided to them when planning their travels.

While travel industry insurance may be beneficial for businesses to manage risks, it does not function as a direct consumer protection mechanism put in place by Ontario's regulatory framework.
