TransUnion Canada is a company that keeps track of how responsible people are with money. They make something called a "credit report" that shows how much money people owe, if they pay their bills on time, and how much credit they have available to use. This information is important because when someone wants to borrow money, like a loan for a car or a house, the bank will look at their credit report to decide if they are a responsible borrower. TransUnion Canada makes sure that all of the information on the credit report is accurate and up-to-date, so that the bank can make a good decision about lending money.
