Cryptocurrency activity in Canada can be tracked through exchange accounts managed by a service provider or through self-custody where the individual controls wallet credentials directly. These two approaches differ in who holds records, how transactions appear, and what documentation is available for reconciliation. Understanding both models is important foundational knowledge for Canadian record-keeping.

What Is an Exchange Account?

An exchange account is one where a service provider holds or manages cryptoassets on behalf of the user. The user typically accesses assets through a login interface and initiates trades or withdrawals through the platform. The exchange maintains internal records of balances and transaction history.

From a record-keeping perspective, exchange accounts often provide structured statements with dates, trade amounts, fees, and deposit or withdrawal details. These statements can be exported and saved for annual reconciliation. The format and completeness of reports vary by platform.

What Is Self-Custody?

Self-custody means the individual controls the wallet credentials required to authorise transactions. Activity is recorded on the blockchain and can be viewed through block explorers or wallet software. The user is responsible for maintaining their own transaction log.

Self-custody records may require more manual organisation because there is no central platform generating annual summaries. Wallet exports, block explorer queries, and personal logs combine to form the documentation.

Record-Keeping Differences

Exchange accounts typically provide transaction histories within the service interface, often exportable as CSV or PDF files. These records can include dates, amounts, fees, and transfer details in a structured format.

Self-custody transactions are recorded on the blockchain and can be viewed through block explorers using wallet addresses. Each transfer may need to be logged individually with its date, amount, fee, and Canadian dollar value at the time.

Canadian residents who use both models may need to maintain records from multiple sources and reconcile transfers between exchange accounts and personal wallets.

Transfers Between Exchange and Wallet

Moving assets from an exchange to a personal wallet is a withdrawal from the exchange's perspective and a deposit to the wallet. Both sides of the transfer should appear in respective records. Matching these entries supports accurate reconciliation.

Network fees for withdrawals may appear on exchange statements or wallet histories depending on how the platform processes the transfer. Noting fees on both sides helps avoid gaps in documentation.

Annual Reporting Considerations

When preparing records for a tax year, Canadian residents may need to combine exchange statements with wallet transaction logs. Transfers between own accounts should be identifiable so they are not double-counted. Trade activity on exchanges and wallet-level transfers each contribute to the overall transaction history.

Educational guidance emphasises starting record collection early rather than reconstructing activity from incomplete sources at filing time.

Security and Record Overlap

Exchange accounts can be targeted through credential theft, while self-custody wallets can be targeted through seed phrase theft. Security considerations differ between models, but both require users to maintain accurate records of their activity.

Loss of access to an exchange account or wallet does not eliminate the need for historical records. Saving exports regularly reduces dependence on platform availability for past data.

An Educational Comparison

The purpose of comparing exchange accounts with self-custody is to clarify how each model affects record-keeping, not to declare one superior. Each involves different trade-offs in documentation convenience, control, and personal responsibility.

Readers who understand both approaches can maintain more complete records aligned with their own activity patterns, without relying on promotional claims from any particular provider.
