To find out how the name Canada came about, we must go back to the 16th century. At that time, the French dreamed of discovering and controlling more land across the world. In 1535 Francois I, King of France, ordered a navigator (航海家) named Jacques Cartier to explore the New world and search for a passage to India.

Cartier first arrived at the Gulf of the St. Lawrence, which he wanted to explore. He did not know

what to expect but he hoped that this Gulf was just an arm of the ocean between two islands. If it

was, he would soon be on his way to the Far East. So he sailed upwards along the St. Lawrence

River. However, instead of reaching Asia he arrived at Quebec or Stadacona, as the Indians called

it. It was at this point that the term “Canada” entered the country’s history. Clearly the word

“Canada” came from an Indian word “Kanata”, which means village. Cartier first used it when he

referred to Stadacona or Quebec. What a huge “village” Canada is!
