Suspicious Transaction Report (STR): Definition + Case Study

Suspicious Transaction Report (STR)

Mandatory FINTRAC report when reasonable grounds exist to suspect money laundering or terrorist financing.

Definition

An STR must be filed within 3 business days of the day the registrant first forms reasonable grounds to suspect a transaction or attempted transaction is related to money laundering or terrorist financing. There is no monetary threshold - a $500 transaction can trigger an STR if the circumstances warrant it. Attempted transactions (where the client did not ultimately complete the transaction) are also reportable. Tipping off the client that an STR has been filed or is being considered is a criminal offence under PCMLTFA.

1
Under the Proceeds of Crime (Money Laundering) and Terrorist Financing Act, a financial entity that receives cash in a single transaction of $10,000 or more must file which type of report?
Outcome 6.1 · click for answer
A.A Suspicious Transaction Report (STR) with CIRO.
B.A Large Cash Transaction Report (LCTR) with FINTRAC within a prescribed number of business days.Correct
C.A Currency Transaction Report with the Canada Revenue Agency.
D.An Unusual Transaction Report with the Office of the Superintendent of Financial Institutions.
The PCMLTFA requires reporting entities to submit a Large Cash Transaction Report to FINTRAC when they receive cash of $10,000 or more in a single transaction, or two or more transactions totalling $10,000 or more within 24 consecutive hours that the entity knows or suspects are related. The report goes to FINTRAC, Canada's financial intelligence unit, not to CIRO, the CRA, or OSFI. This $10,000 threshold is a well-established and well-publicized compliance benchmark.

A Participant's trader has specific knowledge that a client is about to submit a large buy order for 500,000 shares of a small-cap company that will likely move the price significantly. Before entering the client's order, the trader buys 20,000 shares in the firm's principal account. Which UMIR provision does this most directly violate?
Outcome 6.1 · click for answer
A.UMIR 5.3(1); client priority, because the trader is trading alongside the client order.
B.UMIR 10.16; the gatekeeper obligation, because the trader failed to report the order to compliance.
C.UMIR 4.1(1)(a); frontrunning, which prohibits a Participant with specific knowledge of a client order that could reasonably be expected to affect market price from entering a principal order in the same security before the client order is entered.Correct
D.UMIR 2.2(2)(b); ramping, because the trader's purchases create successively higher prices.
UMIR 4.1(1)(a) prohibits a Participant with specific knowledge of a client order that could reasonably be expected to affect the market price from entering a principal or non-client order in the same security (or a related security or derivative) before the client order is entered. Trading the firm's own account ahead of a known client order that will move the price is classic frontrunning. Client priority under UMIR 5.3 is a related but distinct obligation addressing trading alongside an existing client order at the same price. Ramping under 2.2(2)(b) involves successive purchases designed to drive price artificially, which is not the primary characterization here.
