The 2021 Suez Canal obstruction was a six-day blockage of the Suez Canal in March 2021 after the container ship *Ever Given* ran aground and became lodged across the waterway. The incident halted traffic in both directions and disrupted global shipping flows between Asia, Europe, and the Middle East. It became one of the most widely reported shipping disruptions of the year.

Background

The Suez Canal is a major artificial waterway in Egypt connecting the Mediterranean Sea and the Red Sea. It is a critical route for international maritime trade and container shipping.

The obstruction

On 23 March 2021, the *Ever Given* ran aground in the southern section of the canal and became wedged across the channel. Because the area had only one navigation lane, all transits were blocked.

Response and resolution

Salvage crews used tugboats, dredging, and other efforts to free the vessel. The ship was refloated on 29 March 2021 and canal traffic resumed.

Economic impact

The blockage caused major delays to cargo movement and created a backlog of ships at both ends of the canal. Estimates placed the value of trade delayed at billions of US dollars per day.

Key facts

  • The blockage began on 23 March 2021 when *Ever Given* ran aground in the canal.
  • The ship was a 400-metre container vessel with a capacity of about 20,000 TEU.
  • The obstruction stopped traffic in both directions until the vessel was freed on 29 March 2021.
  • Reports estimated that goods worth roughly US$9.6 billion per day were delayed.
  • More than 400 ships were reported waiting during the blockage.

Canadian context

The obstruction contributed to global shipping delays and supply-chain disruption, which affected importers, exporters, and consumers in Canada through delayed cargo and higher freight-related costs.
