Issued Compliance and Enforcement Guidance

Compliance and Enforcement Guidance documents provide guidance, on a forward-looking basis, of MACD’s view of the meaning of specific market rule provisions and their potential application to compliance and other enforcement determinations. These documents take two forms:

  • Statements of Approach – which provide non-binding direction as to MACD’s interpretation of the rules and how they may be applied in given circumstances.
  • Interpretation Bulletins – these are similar to Statements of Approach in terms of general purpose, but are developed and published by the IESO under the authority of the Market Rules, Chapter 1, Section 12. Bulletins are binding on the IESO, subject to the conditions listed in Section 12.1.5 of Chapter 1 of the market rules.
