What is the body of water that separates western quebec from eastern Nunavut?

The Hudson Bay because the Atlantic Ocean goes through the countries and it looks like a bowl so they named it the Hudson Bay. Also, because Henry Hudson traveled through there to find the Northwest Passage Way to get to the Pacific Ocean to trade. Henry's sailors abounded him while a harsh winter came and every thing froze. So they threw him over board he was on his own for a long period of time. Henry Hudson died in the Hudson river named after him.

Hope you had a good time reading my paragraph! :)
