The former Tottenham striker scored twice inside the opening 25 minutes of his first game for the MLS side and does not think England boss Roy Hodgson would be surprised
The striker scored two goals inside the opening 25 minutes of his debut for the MLS side on Saturday as Toronto beat Seattle Sounders 2-1 in their opening game of the new season.
Roy Hodgson will announce his provisional 30-man squad for the tournament in mid-May and Defoe says all he can do is concentrate on his performances for his new side and hope the manager takes note.
"I think the most important thing for me is just to focus on playing here, winning games, and working hard for the team and obviously, trying to score goals," he told reporters.
"Obviously with the England thing, you know obviously it's gonna be at the back of my mind, but I'm sure if someone said to Roy Hodgson 'you know, if you haven't seen, Jermain scored two goals,' then maybe he won't be surprised."
Defoe has 19 goals in 55 appearances for England.
