PIA aircraft PK-781 was grounded in Karachi due to a mechanical problem.
The flight was scheduled to depart Islamabad for Toronto, but was forced to land in Jinnah Terminal Karachi due to a technical issue.
According to PIA Spokesperson Abdullah Khan, the malfunction was minor, but the pilot elected to land instead of continuing the long trip over the Atlantic Ocean.
The flight will now take departure on Saturday at 1 p.m.
