Leonard Sinclair Sparks was born in Waverley, Nova Scotia on March 28, 1939, he was a son of the late Lillian (Williams) Sparks and Harold Sparks Sr.

Lennie came out of the Creighton Street gym in Halifax, Nova Scotia, which was run by the Paris brothers of New Glasgow, Nova Scotia. Lennie Sparks was known as a switch hitter in boxing because he could knock opponents out with either hand.^[3] He once told Hugh Townsend^[4] how training with Keith Paris^[1] at the Creighton Street gym helped him grow into a hard puncher with a knack for good defence.^[5]

He went on to be trained by Thomas George "Young Tom" McCluskey^[6][1] who would help Sparks take both the Canadian junior welterweight and Canadian welterweight titles. Lennie Sparks turned pro on May 10, 1956 in Halifax, Nova Scotia, winning his pro debut against Keith Paris by knockout.^[7] On October 6, 1959, Sparks knocked out Jackie Hayden of Westville, Nova Scotia in Pictou County to win the Canadian junior welterweight title.^[8] In his next fight he would score a TKO over Bernie Raines in Halifax, Nova Scotia before taking the opportunity to fight his first bout in the United States.

The fight would go all ten rounds and result in a unanimous decision loss for Lennie Sparks.^[14] The president of the Canadian Professional Boxing Federation told Nanaimo Daily News that Sparks was "lucky" he was not seriously injured and should not have been allowed to fight.^[15]

After a nearly eight-month layoff Lennie Sparks would fight Jim Meilleur in another non-title bout and lose a ten round decision in Summerside, Prince Edward Island.^[16]

On May 11, 1967, Sparks would lose his Canadian welterweight title through a unanimous 12-round decision in favor of Fernand Simard at the Granby Arena in Granby, Quebec.^[17] Despite his loss, the Canadian Professional Boxing Federation would declare the fight with Fernand a non-title bout and Sparks was still regarded as the champion.^[18] The CPBF then ordered Sparks to defend the title against the top contender Joey Durelle.^[19] He would officially lose his Canadian welterweight title to Joey Durelle of Baie-Sainte-Anne, New Brunswick through a unanimous decision in Fredericton.^[20] 5 years after the title loss, the former Canadian welterweight champion would return to the ring a final time to fight Jerry Wells of Cleveland, Ohio, knocking him out in the sixth round in Halifax, Nova Scotia.^[21]

Sparks career would span from 1956 to 1972. The Nova Scotian boxer fought in 40 bouts and finished with a record of 28(17 KOs)-10-2.^[1] He was once ranked the 10th welterweight in the World.^[3]

Leonard Sinclair "Lennie" Sparks died on March 19, 2021, in Halifax, Nova Scotia, Canada, at the age of 81.

Charles R. Saunders, the author of the 1990's book Sweat and Soul also wrote: "...a brawl broke out in the audience while he was fighting in the ring. Lennie turned to see if anyone he knew was involved. Next thing he knew, he was on the canvas, listening to the end of the referee's 10-count. For the rest of his career, Sparks concentrated on what was happening inside the ropes."
