And his contribution to the test victory has been applauded by Cardiff Blues director of coaching Dai Young.
"Chris really proved his worth, not just in the way he scored a difficult try but in his contribution throughout the game," he said.
Young, who also made his debut for Wales at the age of 19 in 1987, added: "Playing for Wales at that age is not easy, particularly when Chris has only had a few senior games for the Blues.
"But he proved he has the talent and pace to compete at test level and I've no doubt that Chris is a rugby star in the making."
Czekaj was one of several Blues to appear for Wales against Canada. Fellow winger Rhys Williams scored a try in the match and Mike Phillips, who will join the Blues next season, was a powerful force at scrum half.
Forwards Robert Sidoli, Rhys Thomas, John Yapp and Robin Sowden-Taylor also played their part in Wales' success.
"I was delighted for all the boys who once again proved the strength of the Blues playing squad," said Young.
