Since switching to represent Canada in 2010, Spring has won nine world cup medals, including two gold and two crystal globes in both the two-man and four-man events. He has represented Canada three times at the Winter Olympic Games, with a best result of 5th in the two-man competition with brakeman Jesse Lumsden.
Spring debuted on the World Cup tour for Canada in 2011, finishing 17th in the two-man event in Cesana, Italy.
He was involved in a catastrophic crash in January 2012 during the 2011–12 Bobsleigh World Cup in Altenberg, Germany, which put him in hospital for eight days.[1] After having his skin shredded and a piece of wood the size of a kitchen knife embedded in his back, Spring considered retiring but later returned to the track in April 2012.[1] He said of his fear of lost skills on his return, "I was really afraid I'd get back in the driver's seat and not know what to do. Or I would get halfway down the track and start freaking out." Yet he said that he felt few ill effects.[1]
