Isadore "Issy" Sharp, OC (born October 8, 1931) is a Canadian hotelier and philanthropist.

His father, Max, a devout Torah scholar, was a Polish Jew who emigrated from Poland to the British Mandate of Palestine in 1920[2][circular reference],[3][4] and finally to Toronto five years later.

He also would be able to realize proceeds from a 1989 incentive plan that would pay him $288 million; the company's headquarters would remain in Toronto.

He first met Terry Fox when the latter arrived in Montreal in June 1980 during his trek across the country to raise money for cancer research.

Sharp invited Fox to rest in one of the city's Four Seasons hotels for a week before resuming his run, helped pay for his cancer treatment, and later pledged to contribute to research funds on his behalf.

[7] Sharp and his wife are prominent Canadian philanthropists, having made significant donations to many sources including the Four Seasons Centre for the Performing Arts,[11] the Ontario College of Art and Design,[12] Mount Sinai Hospital,[13] and the Hebrew University of Jerusalem.
