How to File STRs That Hold Up in an Audit
STR quality and timeliness are among the most scrutinized areas in FINTRAC examinations.
Learn how to assess suspicion, meet the 'as soon as practicable' standard, and build a workflow that reduces rework and regulatory risk.
An STR must be filed when there are reasonable grounds to suspect, based on facts, context, and indicators, that a completed or attempted transaction is related to:
There is no monetary threshold for STRs. A small transaction can still require reporting if the facts and context support suspicion.
The filing standard is not a fixed numeric deadline like threshold reports. Once your team completes its measures and reaches reasonable grounds to suspect, STR preparation and submission should move as a priority and be filed as soon as practicable: urgent, not whenever convenient.
Long gaps between suspicion and filing need documented justification; unexplained delay is hard to defend.
FINTRAC deliberately uses practicable (not practical): file as soon as doing so is feasible after assessment and preparation, not at a loosely convenient time.
Delays between suspicion and filing without documented justification are a common examination finding.
A defensible STR process maps clearly to four core measures:
(This is where most teams break down.)
Before filing, validate:
Each reporting obligation is independent. Filing an STR does not satisfy LCTR, LVCTR, or EFTR requirements.
If suspicious activity also triggers another report type, those reports are filed in addition to the STR. Depending on the event, this can include LCTR, LVCTR, EFTR, and where applicable LPEPR obligations.
Manual STR workflows break under scale because data, review notes, and decision rationale are spread across inboxes and files. Standardized workflows improve consistency and help produce review-ready records when requested.
Comply+ includes proprietary aiSTR™ technology that helps surface suspicious activity and drafts FINTRAC-compliant STR narratives aligned with regulator expectations, so your team can focus on review and sign-off. Need someone else to run it? Our Managed Filing Service handles setup, filing, and monthly summaries: you send the data, we handle preparation and filing. Comply+ also includes access to Comply+ Academy for FINTRAC compliance training.
No. STR obligations are based on suspicion, not transaction size.
Yes. Attempted transactions can be reportable where suspicion criteria are met.
Clear facts, indicators, context, timeline, and reasoning that explain why suspicion was reached.
No. Human assessment remains essential. Software supports consistency, speed, and evidence quality.
Timeliness, rationale quality, record completeness, and whether your controls detect and escalate reportable activity consistently.
FINTRAC enforcement is intensifying. Recent penalties demonstrate that compliance failures result in significant financial consequences, with Bill C-2 increasing maximum penalties to $20 million for entities.
FINTRAC has imposed significant Administrative Monetary Penalties (AMPs) for compliance failures across multiple sectors.
December 2025 — Toronto, Ontario
Multiple compliance failures including no effective compliance regime, no proper risk assessment, and failures to submit EFT and LCT reports.

2,593 violations including 1,068 unreported STRs, 1,518 unreported LVCTRs, and failure to comply with Ministerial Directive on Iran.

Unregistered foreign MSB, 2,952 unreported LVCTRs, and 33 unreported STRs linked to darknet marketplaces and illicit chemical trade.
