McIsaac, a 17-year-old defenceman for the Halifax Mooseheads, is among a group of 44 players – four goaltenders, 16 defencemen, and 24 forwards – vying for a spot on the team.
Following the five-day selection camp, the team will leave for the Czech Republic in early August to compete at the Ivan Hlinka Memorial Cup.
McIsaac, who lives in Cole Harbour, had a highly successful rookie season in 2016-17 in the Quebec Major Junior Hockey League. He set a franchise record for points by a 16-year-old blueliner with 32 during the regular season.
He was also the recipient of the Q-league’s Raymond-Lagacé Trophy as Defensive Rookie of the Year.
In April, he played for Canada at the world under-18 championship in Slovakia.
Joining McIsaac at the under-18 camp next month will be Mooseheads forwards Benoit-Olivier Groulx and Raphael Lavoie and goaltender Alex Gravel.
