It is TD Canada, but they know I am US resident/citizen and they told me that they only sent the document to IRS, and not CRA. The tax slip is for IRS.
If you are still unsure, you can contact the Canada Revenue Agency (CRA) and confirm it with them.
If you are in Canada or the United States, you can call the CRA at 1-800-959-8281. If you are elsewhere, you can call 613-940-8495. This page has more ways to contact the CRA: Contact the Canada Revenue Agency
