Since both India and Canada were British dominions at that time, the Indians should have had the right to enter Canada. But the Canadian government of that time put in place various clauses in laws to bar Indians from entering Canada.
The Komagata Maru, which entered Vancouver harbour on May 23, 1914, was forcibly sent back to India after two months. On reaching Budge Budge in Calcutta in September 1914, the passengers were subjected to firing by British Indian police in which 19 of them were killed. In his apology in the House of Commons on Wednesday, Trudeau said: "Canada's government was, without question, responsible for the laws that prevented these passengers from immigrating peacefully and securely. For that, and for every regrettable consequence that followed, we are sorry." In his statement on Saturday, Swarup said that Trudeau's gesture reflected “Canada’s commitment to the values of pluralism and multiculturalism, which India fully shares”.
