Grant must disclose the nature and extent of his involvement with the Hockey Association and how it may affect his availability, reputation, or potential for conflicts of interest. The firm may approve, reject, or impose conditions on Grant's outside activity.

Orel's goal is to build emergency savings, which means he needs a flexible and accessible account that does not penalize withdrawals. A TFSA is more suitable for this purpose, as it allows tax-free withdrawals at any time and does not affect other income-tested benefits. An RRSP, on the other hand, is designed for long-term retirement savings, and withdrawals are subject to income tax and withholding tax. Moreover, RRSP withdrawals reduce the contribution room permanently, and may affect eligibility for government benefits such as the Canada Child Benefit or the Guaranteed Income Supplement.

According to the MFDA rules, a Member or an Approved Person cannot accept or act upon a general power of attorney or other similar authorization from a client in favour of the Member or Approved Person, unless the client is a spouse, parent, or child of the Approved Person and certain conditions are met. However, a Member or an Approved Person can accept a limited trading authorization from a client, which allows the Member or Approved Person to execute trades on behalf of the client, but not to engage in any discretionary trading. Therefore, Josephine can accept a limited POA from her brother, as long as she does not make any investment decisions without his consent.
