Do I, As The Agent For A Reporting Insider, Have To File A Power Of Attorney For Insider Reports Filed On SEDI?

No. However, if you, as an agent, are filing an insider report in paper format in certain circumstances (see question 4.3.7), you still need to file with the relevant securities regulatory authority a power of attorney. However, an agent does not need to file a power of attorney for an insider report of an individual that is filed in paper format under the temporary hardship exemption.
