Final answer:
The largest liability for the Bank of Canada is Canadian dollars in circulation. Bonds are considered assets for banks and when government bonds are purchased, they are recorded as assets due to their expected returns.
Step-by-step explanation:
The largest component of the liabilities of the Bank of Canada is C) Canadian dollars in circulation. This is because the issuance of currency is a central function of the Bank of Canada, and the Canadian dollars that are in physical circulation represent a liability for the central bank.
Bonds, as mentioned in the reference material, are considered assets for a bank. When a bank, such as the hypothetical Safe and Secure Bank, buys bonds, especially those issued by governments such as the Government of Canada, these bonds are recorded as assets because they are expected to be paid back with interest in the future. On the other hand, loans to private individuals, government securities, and deposits from various entities are different components of a bank's balance sheet that may either represent assets or liabilities depending on the context. However, for the central bank, the currency it has issued is the principal liability.
