In the Netscape menu bar, click on "Yahoo!" and select "Show/Hide Y! Toolbar."

Internet Explorer Users:

You can't hide the Yahoo! Canada toolbar in Internet Explorer, but you can move it so that it doesn't use as much space:

1. Look for the thin vertical bar directly to the left of the "Y!" button.
2. Click and drag this bar with your mouse to move the toolbar around the top of Internet Explorer.
