I run a membership website and occasionally people ask to cancel their memberships. After writing emails back to notify them of their cancellations, I realized that neither canceled (one word) or cancelled (two words) triggered a spell check errors.
So, I had to research which is correct: canceled or cancelled?
It turns out, the answer is: BOTH.
Canceled with one “l” is more common among U.S. Americans, while two “l’s” is often used in British, Canadian, and Australian English.
This logic also applies to canceling/cancelling and cancelers/cancellers.
There are, however, always two l’s in cancellation.
