The Canadian-born Jebbison, who is eligible to represent England and Jamaica through his parents, spent years as an England youth international and went to the Under-20 World Cup with the Three Lions in 2023.
Canada Soccer told Reuters Jebbison cannot officially play for Canada until his "Change of Association" has been approved by FIFA.
According to a source familiar with the situation who spoke on the condition of anonymity, Canada Soccer expects Jebbison's one-time transfer to be completed before naming a final 23-man roster and potentially even this week.
In 2021, the then-17-year-old Sheffield United striker became the youngest player to score in his first Premier League start in a 1-0 win over Everton.
Jebbison has not scored in eight Premier League appearances off the bench for Bournemouth this season but does have two goals in two FA Cup appearances.
