Toney won the 12-round bout in a unanimous decision Saturday, with the judges scoring the fight 116-111, 116-111 and 115-112 in favor of the American.
With the victory, Toney becomes just the third fighter after American Roy Jones Jr. and British boxer Bob Fitzsimmons to win a heavyweight crown after being a middleweight champion.
Ruiz, who first took the WBA belt from Evander Holyfield in 2001, retired after his sixth loss in 48 pro bouts.
