(WJLA) - One of the biggest winners in Canadian lottery history is giving his entire jackpot away.

The CBC reports that Tom Crist, a former electrical wholesale executive who lives in Calgary, won $40 million in a Western Canada Lottery drawing last year. He kept it a secret until very recently, when he announced that the entire prize was going to charity.

Crist's longtime wife died of Cancer in 2011, and the CBC says Crist plans to leave the enormous jackpot to a pair of Alberta cancer centers and charities.

"I was hoping that I could just somehow move it from the lotto corporation into my trust account and not have the media," Crist said.

On Tuesday, in America, Mega Millions will draw for one of the largest prizes in United States history. It currently sits at $586 million.
