Getty Images has been sending letters out like this for some time. Search online and you will find a lot of information on how people are handling the letters. You mention Getty Images Canada sent you the letter. Copyright laws are enforced only within the country that they are in force so the question is whether Getty Images Canada is alleging a violation of Canadian law; what that Canadian law says; and whether your website use of the images at issue violated those laws. Someone needs to look at the facts and the law. However, keep in mind that using images protected by copyright without authorization can expose you to liability so it is important to make sure that you clear everything you use. If you buy a business, you should get a warranty from the seller that nothing infringes anyone's rights and if it does, they will indemnify you.
