One of the measures of control is that a Canadian charity monitor and supervise its activities carried on by the intermediary.

In CRA’s Guidance “Using an Intermediary to Carry out a Charity’s Activities within Canada” it notes:

“5.4. What is monitoring and supervision?
Monitoring and supervision is the process of receiving timely and accurate reports, which allows a charity to make sure that its resources are being used for its own activities. Depending on factors such as the size, nature, and complexity of an activity, the reporting methods (as stated in any written agreement) can take many forms, including the following:
• progress reports
• receipts for expenses and financial statements
• informal communication via telephone or email
• photographs
• audit reports
• on-site inspections by the charity’s staff members”
