Hudson's Bay Company is a very old store that was started a very long time ago. In fact, it is one of the oldest stores in the world! It started in Canada, which is a country way up north above the United States.
A long time ago, when people from other countries began to visit North America, there were a lot of animals there that those people had never seen before, like beavers and buffalo. The Hudson's Bay Company was started to buy those animals' fur, which is really soft and pretty, and then sell it to people in other countries who wanted to make fancy clothes and hats.
For a very long time, the Hudson's Bay Company was the most important store in Canada. They sold things like fur and blankets, but they also sold guns and food and other things that people who lived in Canada needed.
Nowadays, the Hudson's Bay Company is a store that sells a lot of different things like clothes, furniture, appliances, and toys. It's like a really big mall! But the Hudson's Bay Company is still very important to Canada, and a lot of people go there to shop and find things they need.
