Connor McDavid is expected to be taken with the first pick and is regarded as a generational talent.
The 18-year-old centre scored 44 goals and finished with 120 points in only 47 OHL games this season for the Erie Otters, while also helping Canada win gold in the world junior championship.
McDavid is considered by many to be the best player to come along since Sidney Crosby in 2005.
Boston University centre Jack Eichel, 18, is also likely to be selected early in the first round. In 40 games as a freshman, he tallied 26 goals and 45 assists.
The draft will take place on June 26 in Florida.
