There are 6 towers and a pavilion that are part of Toronto-Dominion Centre. TD Bank uses the tallest tower, Toronto Dominion Tower, and the pavilion as as bank branch. They might have some staff in the other towers as well.

But what is it the corporate headquarters for? I doubt if the corporate headquarters of any corporation is in all of these buildings. So, in keeping with the thread title, what is the corporate headquarters?

If we're doing the Big 5, we'd need to include the largest Canadian bank, Royal Bank. Royal Bank of Canada occupies both of the gold towers. You can see a bit of TD Bank's HQ (black tower) and CIBC's HQ (silver tower on the left) in the first photo.

When I first saw photos of it I thought it was a bit garish. In person, it's spectacular. It doesn't get as much attention as some of the other buildings, but it's a gem. Royal Bank Plaza will age well too.
