What is the role of customs at Vancouver International Airport?

The role of customs at Vancouver International Airport is primarily to regulate and check goods and travelers entering Canada. This involves ensuring that all items being brought into the country comply with Canadian laws and regulations, including import restrictions and duty assessment. Customs officials are responsible for inspecting luggage, documentation, and sometimes the travelers themselves to prevent illegal goods, contraband, or any unsafe items from entering the country. Their work is crucial for national security and public health.

The other roles mentioned in the choices, such as issuing boarding passes, managing parking facilities, and overseeing baggage claim, are functions typically handled by airline staff, airport operations, and ground services rather than customs officials. Each of these areas plays an important part in the overall airport experience, but they do not pertain directly to the duties and responsibilities of customs.
