Kenneth Leishman, also known as the Flying Bandit or the Gentleman Bandit was a Canadian criminal responsible for multiple robberies between 1957 and 1966. Leishman was the mastermind behind the largest gold theft in Canadian history. This record stood for over 50 years, until it was surpassed by the Toronto Pearson airport heist in 2023. After being caught and arrested by the Royal Canadian Mounted Police (RCMP), Leishman managed to escape twice, before being caught and serving the remainder of his various sentences.

On April 17, 2023, a grand theft occurred at Toronto Pearson International Airport in Canada, with over C$20 million worth of gold and cash in foreign currency being stolen. In the evening of Monday, April 17, a container which contained goldbars and foreign currency was offloaded off an inbound aircraft and transferred to an Air Canada holding facility at the airport where Air Canada staff were tricked by a forged shipping document to load it onto a getaway truck. Nine people have been charged in relation to the heist.
