The 37-year-old man was found drunk shortly after 7:00 am (1200 GMT) in the cockpit of the plane he was supposed to pilot to Cancun, Mexico.
Before the flight was schedule to take off, the crew and other airline staff noticed the pilot's behaving strangely before he fainted in the cockpit. They then alerted the authorities.
The pilot was subsequently escorted out of the plane and was placed in jail, police said.
The authorities said the pilot had more than three times the authorized amount of alcohol (0.08 percent in Canada) in his body two hours after his arrest.
The pilot was charged with being in control of an aircraft while being impaired, and faces other charges.
