Narrative:

Air carrier X from toronto, canada (yyz) to kingston jamaica (mkjp), crossed the cleveland ARTCC buffalo sector boundary climbing through 16,500 to FL230. No handoff had been initiated by the toronto center controller. I was the buffalo sector controller. I advised the toronto controller of the error. By the time the aircraft was positively identified, the aircraft was 15 mi within my airspace. None of the aircraft I was working, at the time, were an immediate factor with the air carrier X aircraft. A possible cause of the error was the high traffic density and complexity being worked by both the toronto and cleveland center controller.
