Alex Massie won a silver medal in the snowboarder X adaptive on Sunday, missing out on gold by just 0.711 seconds to Finland's Matti Suur-Hamari.

This is Massie's second X Games medal, as he won a bronze in the same event last year, his rookie season. 

Massie is an amputee, his right leg is amputated below the knee. He lost his leg in 2011 in a boating accident when a propeller struck his foot five times.

Canada finished the X Games with 11 total medals, including five gold, four silver and two bronze.
