The complainant alleged that the Trans Mountain Corporation (TMC) had improperly withheld information under many provisions of the Access to Information Act in response to an access request. The request was for records related to the initial application and approval of the Trans Mountain Pipeline in the early 1950s. The allegation falls under paragraph 30(1)(a) of the Act. During the investigation, the complainant reduced the scope of the request and excluded subsection 19(1) (personal information) from the scope of the investigation. TMC failed to identify which specific information within the records was withheld and did not establish how any of the withheld content met the criteria for exemption under the Act. Furthermore, TMC did not demonstrate that providing the complainant with a copy of the records would be unreasonable under subsection 8(1) of the Regulations. The Information Commissioner ordered TMC disclose the Records at Issue to the complainant by a specified deadline. TMC gave notice to the Commissioner that it would implement the order. The complaint is well founded.
