The complainant alleged that the Canada Mortgage and Housing Corporation (CMHC) had improperly withheld information under paragraph 18(a) (government trade secrets, government financial, commercial, scientific or technical information), paragraph 18(b) (competitive position of government institutions, negotiations by government institutions), subsection 19(1) (personal information), paragraph 20(1)(b) (confidential third-party financial, commercial, scientific or technical information), paragraph 21(1)(a) (advice or recommendations), paragraph 21(1)(b) (accounts of consultations or deliberations) and section 23 (solicitor-client privilege) of the Access to Information Act. This was in response to an access request for final versions of documents mentioned in the response to a previous access request. The complaint falls within paragraph 30(1)(a) of the Act.

The scope of the complaint was reduced to remove subsection 19(1), section 23 and instances where paragraph 20(1)(b) was applied to withhold certain third-party information.

During the investigation, CMHC disclosed some information it had withheld under paragraphs 18(a), 18(b), 21(1)(a) and 21(1)(b). CMHC showed that it met all of the requirements of these exemptions where it maintained them.

The third parties did not provide any representations and CMHC could not show that it met all the requirements of paragraph 20(1)(b).

The Information Commissioner ordered that CMHC disclose all information at issue withheld under paragraph 20(1)(b).

CMHC gave notice that it would implement the order.

The complaint is well founded.
