A 39-year-old London, Ont. father has died following a skiing accident at Blue Mountain Resort in Collingwood on Saturday.

Tim Smuck was involved in a collision with another skier before he hit a tree, according to his brother-in-law Orval Thompson, who witnessed the crash.

While Smuck was wearing a helmet, OPP say he was transported to hospital where he was pronunced dead.

Smuck leaves behind two sons, Ace, three, and one-year-old Lincoln, as well as his fiancee Holly Thompson.

Thomson told CTV Barrie on the weekend, "I spoke to them briefly this morning, and (I) just said the same thing, dad had a big fall...(he) was very hurt, and so he's gone on to heaven.”

Four years ago Smuck and his fiancée lost their 12-day-old son, while late last year Holly was diagnosed with breast cancer.

Still, family and friends say Smuck was vibrant and fun-loving, a person who lit up every room with his presence.

Also known as Toyota Tim, the 39-year-old was a long-time employee at Toyota Town, where co-workers say it's going to be a difficult loss.

Friend Chelsea Wakefield says, "I hear his laughter, I see how dedicated he was not just to his family, but his job. He just put his entire self into everything he did."
