Igor Zaitsev, 42, a skydiving student, died Sunday after crash-landing in Baldwin, Ont., about an hour north of Toronto.
Zaitsev was alive after he hit the ground, but suffered major traumatic injuries. He was later pronounced dead in hospital.
A day later, his teenage son, Dmitry Zaytsev, still can't believe his father is gone.
"For me it was a pretty intense shock and I broke down," he told CBC News in an interview on Monday.
The 19-year-old said that his two-year-old sister is going to grow up without her dad and his mom will have to live without her husband.
Doomed man was getting back into sport
Igor Zaitsev had originally got into parachuting in the 1980s and was just getting back into the extreme sport at the time of his death.
He had made 10 jumps since last fall.
Police believe Zaitsev's death was a tragic accident. However, the coroner is looking into the cause of the crash landing and has called in experts from CFB Trenton to help.
"The coroner has questions as to whether or not the parachute equipment was in fact, serviceable and operated correctly," said Warrant Officer Martin Lodder in an interview with CBC News.
