In a 2020 interview with Hockey Manitoba, he explained that sports were always an important part of his own life, making it natural to encourage his children to remain active.
How Jason Mateychuk Influenced Denton’s Hockey Career
Jason played an important role in helping Denton develop discipline, competitiveness, and a strong work ethic.
Growing up in Dominion City, the family had access to outdoor spaces where the children could play baseball, hockey, and other sports.
Jason helped create a backyard baseball diamond where his sons frequently competed against one another.
He also supported Denton’s development through youth hockey programs, including the Southern Steelers and Eastman Selects.
Traveling to practices was challenging because the family lived in a small community with limited access to high-level hockey facilities.
During his teenage years, Denton regularly traveled between one and one and a half hours to attend practices.
Jason and Keela coordinated these trips while supporting the sporting activities of their other four children.
In the official 2022 CHL/NHL Top Prospects Game biography, Denton identified his father as the most influential person in his hockey career.
Jason Mateychuk Attended Denton’s NHL Debut
One of the family’s most memorable experiences occurred on December 23, 2024, when Denton made his NHL debut against the Montreal Canadiens.
According to the Columbus Blue Jackets, Denton called his father the day before the game to explain that he had been promoted from the Cleveland Monsters.
Jason initially thought his son was calling to arrange travel home for Christmas.
Instead, he learned that Denton would be making his NHL debut.
Jason and the rest of the family quickly arranged flights to Columbus.
Both parents and all four siblings arrived at Nationwide Arena in time for pregame warmups.
Jason expressed enormous pride in watching his son achieve the dream he had pursued since childhood.

According to Hockey Manitoba, Keela won the 2003 Manitoba Women’s Half Marathon, approximately 11 months after giving birth to her oldest son, Maddux.
Her sporting experience helped create an environment where physical activity became an important part of everyday family life.
Keela also contributed directly to Denton’s hockey development by teaching skating techniques.
How Keela Mateychuk Helped Denton Become a Better Skater
Keela’s experience in figure skating and power skating was particularly important in helping Denton develop his skating abilities.
In a 2026 interview featured by The Hockey News, Mateychuk credited his mother for teaching him important skating fundamentals during childhood.
Her guidance helped him develop the balance, agility, and edge control that later became strengths of his playing style.
As a defenseman, Mateychuk relies heavily on skating ability to move the puck, join offensive plays, and maintain defensive positioning.
He has repeatedly acknowledged that his mother contributed significantly to these skills.
Keela also supported all five children’s sporting commitments, regularly attending practices and games.
In a 2020 Hockey Manitoba feature, Denton explained that his mother rarely missed one of his games unless she was attending a game involving another sibling.
