CRA discusses the documentation of a loss from the collapse of a crypto exchange

After the taxpayer for a number of months had been trading on a daily basis in cryptocurrencies through an account held at a major cryptocurrency exchange platform, the platform went into bankruptcy on the discovery of fraud. All documentation relating to the daily transactions was on the platform, and the taxpayer no longer has access to that information.

CRA provided a detailed list of documents that the taxpayer in these circumstances might be able to obtain in order to support the taxpayer’s claimed loss.
