Ontario Securities Commission (OSC) staff concluded that QuadrigaCX’s losses largely reflected years of fraud and asset depletion—not cryptocurrency made inaccessible when CEO Gerald Cotten died. The review found that the exchange’s claims about cold storage were misleading, but it did not establish that every wallet was emptied or account for every missing dollar. Its conclusions are staff findings, not findings tested before an OSC hearing panel or a court.
Were QuadrigaCX’s wallets emptied before Cotten died?
The later OSC review substantially changed the story’s focus. The public explanation centered on Cotten’s death and the possibility that he alone held keys needed to access the exchange’s cryptocurrency. OSC staff instead concluded that most of the asset shortfall resulted from Cotten’s fraudulent conduct while he was alive. The report described the case as “an old-fashioned fraud wrapped in modern technology.” Read the OSC’s 2020 staff review.
That conclusion does not mean investigators proved that every Quadriga wallet was emptied before Cotten’s death. The review describes misleading custody claims, losses, asset transfers and gaps in the records; it also says some transactions and the ultimate fate of some funds could not be established. The supportable conclusion is that the lost-keys explanation does not account for most of the reported losses.
What Quadriga promised about custody—and what the OSC found
Quadriga told clients that most bitcoin was held in cold storage, meaning offline, and Cotten claimed the cryptocurrency was kept in secure offline multi-signature wallets. A multi-signature wallet requires more than one private key to authorize access. These descriptions were assurances about how client assets were supposedly protected; they are not evidence that Quadriga actually held the corresponding assets.

OSC staff found those claims “untrue and misleading.” The exchange primarily used hot wallets—wallets connected to the internet—and accounts at other crypto trading platforms. Cotten also moved client assets to external accounts. The OSC’s account of Quadriga’s launch and platform operations explains the gap between the public custody claims and the practices staff identified.
Clients also could not infer from an account balance that Quadriga held an equivalent amount of cryptocurrency for them. Client assets were pooled, and the balance displayed in an account was an accounting entry, not proof of a matching coin held in reserve for that individual.

How the reported shortfall accumulated
OSC staff attributed the shortfall to several forms of misconduct and mismanagement, rather than a single failed wallet. The following amounts are Canadian dollars and are figures reported in the OSC’s 2020 review:
| Component | Amount and OSC assessment |
|---|---|
| Fraudulent trading on Quadriga | Approximately $115 million; Cotten used aliases and fictitious balances to trade against clients. |
| Trading client assets on other platforms | $28 million lost on three external crypto platforms. |
| Personal use | Millions more; the review identifies this as an additional source of losses. |
| Client shortfall overall | At least $169 million in collective client losses, after $46 million in assets were recovered or identified for clients. |
In the trading scheme, fictitious balances allowed Cotten to trade with clients as if he had cryptocurrency or funds he did not actually possess. When prices moved against those positions, real losses accrued. Deposits from other clients were then used to cover withdrawals and earlier losses. The OSC review says Cotten’s activity contributed approximately $115 million to the shortfall; it does not present every missing asset as a fully traced transaction. The review’s findings and figures provide the underlying account.

Why Cotten’s death exposed a crisis rather than caused it
The chronology in the OSC review indicates that Quadriga was already in severe difficulty before Cotten died on December 9, 2018. From March 2018, new deposits were being redirected immediately to fund other clients’ withdrawals, while real asset outflows exceeded inflows. The exchange owed about $215 million and had almost no assets to cover its liabilities; OSC staff concluded that it likely would have collapsed even if Cotten had lived.
- 2016 onward: Cotten had sole control of client crypto assets, and Quadriga did not keep proper accounting records, according to the review.
- 2017–2018: Cotten used aliases and fictitious account balances to trade against clients, while real losses were covered with other clients’ deposits.
- 2018: A Canadian Imperial Bank of Commerce-related freeze made $26 million inaccessible. The OSC treated this as a contributing problem, not the principal explanation for the much larger shortfall. Staff also found an offshore payment processor account balance of $12 million in April 2018 but could not establish what happened to it or find records showing it was returned.
- December 9, 2018: Cotten died in India.
- January 14, 2019: Quadriga announced his death.
- February 5, 2019: Quadriga ceased operations and sought creditor protection.
- June 11, 2020: The OSC published its staff review.

What the investigation established—and what remains uncertain
OSC Enforcement Branch staff reviewed data from more than 368,000 client accounts and over six million individual transactions. They also examined thousands of related emails, banking and payment-processor records, blockchain transactions and records from other crypto trading platforms. Staff calculated client balances and the cumulative effect of Cotten’s trading with fictitious assets.
The review was substantial, but it was not a complete reconstruction of every transaction. Quadriga lacked proper accounting records from 2016 onward; staff did not review Cotten’s encrypted devices; some records may have been accessible only to him; wallet addresses are generally anonymous; and jurisdictional barriers prevented staff from obtaining evidence from three platforms. The report says staff nevertheless confirmed that Cotten moved client assets to other platforms and traded with them. These limits matter when interpreting claims about precisely which wallets were emptied and where each missing asset went. The OSC explains its review methods and limitations.

Over 76,000 clients were owed a combined $215 million, the OSC reported. Ernst & Young recovered or identified $46 million in assets for clients, leaving collective losses of at least $169 million. The OSC’s conclusions are those of staff and, as the report states, “have not been tested before the OSC tribunal or a court.”
