When a corporation agrees to issue or prepares a selling instrument for flow-through shares (FTSs) or flow-through warrant (FTWs), it must apply to the CRA for an identification number.

A Selling Instrument T100 Identification Number (SITIN) or T100 Identification Number (TIN) is assigned for identification purposes only. It does not guarantee:

• that the shares are FTSs;
• that the agreement meets any or all of the requirements of the Income Tax Act with respect to FTSs;
• that any or all specified expenses are eligible for renunciation; or
• that the CRA accepts the allocation of the price between the shares and the warrants.

A renunciation (T101A) is not valid unless a valid identification number has been issued.
