Graham was born in Brampton, Ontario, Canada. Her father, a Jamaican born Canadian, instilled in Graham a strong identification with Jamaican music and culture. When Graham was young, her father sparked her interest in opera by taking her to see a Leontyne Price recital. Her passion in opera grew while attending high school at the Etobicoke School of the Arts. While in Canada, Graham was awarded first place in the Jeunes Ambassadeurs Lyriques Competition and received the coveted Jean Chalmers prize in the Canadian Music Competition.
