So imagine a really long hallway, like the ones you see at school or a big building. The Quebec City - Windsor corridor is like a really long hallway that connects cities and towns from Quebec City all the way down to Windsor.
People travel through this corridor using cars, buses, trains, and even planes! It's like a really important hallway because it connects big cities like Montreal, Toronto, and Ottawa.
The corridor is really important for trade and transportation because it connects Canada's biggest provinces: Quebec and Ontario. And lots of goods, like food, clothes, and electronics, are transported through this corridor from one city to another.
It's kind of like when you share your toys with your friends at school. The Quebec City - Windsor corridor is like a hallway that helps cities and towns share things with each other, like toys, but on a much bigger scale.
