Under TRESA in Ontario, what is the minimum disclosure requirement when representing a commercial property seller?

Option A: Verbal disclosure of representation at first contact

Verbal disclosure alone is insufficient under TRESA. The legislation specifically requires written disclosure to create a clear, documented record of the representation relationship. Verbal disclosure lacks the permanence and clarity that written disclosure provides, making it inadequate for meeting TRESA's consumer protection standards.

Option C: Disclosure only required if conflicts of interest arise

This is incorrect because disclosure is required for all representation relationships, not just when conflicts arise. TRESA mandates proactive disclosure before providing services, regardless of whether conflicts exist. Waiting until conflicts emerge would leave clients uninformed about the nature of their representation during the initial stages of the relationship.

Option D: Disclosure required only at the time of offer presentation

Waiting until offer presentation is too late under TRESA requirements. Disclosure must occur before providing any services, which typically happens much earlier in the relationship than offer presentation. This timing ensures clients understand the representation arrangement from the beginning of their professional relationship with the registrant.
