Canada Post marks 100th-year anniversary of the Komagata Maru incident with new commemorative stamp One hundred years ago, on May 23, 1914, the Komagata Maru, a Japanese steamship, arrived in Vancouver's Burrard Inlet with 376 passengers, all British subjects, mostly Sikhs from Punjab, India. Under the era's exclusionary immigration policies, the passengers were denied entry, and the ship was forced to return to India. In connection with Asian Heritage Month, Canada Post has issued a new stamp marking the centennial of this event, while also recognizing the strides Canada has made toward creating a more tolerant and diverse society.
