Holland, a centre, will report to the Maple Leafs and Staubitz has been assigned to the American Hockey League's Marlies.
The Ducks receive a 2014 third round pick — it could become a second round pick if certain conditions are met — and Anaheim's 2014 seventh round pick, which was originally acquired by Toronto in a trade for David Steckel.
Holland, a 22-year-old native of Caledon, Ont., was originally Anaheim's first choice, 15th overall, in the 2009 Entry Draft. The six-foot-two, 194-pound centre played four games for Anaheim this season, scoring one goal and adding two penalty minutes.
In 10 games with the AHL's Norfork Admirals he registered a team leading nine points (five goals, four assists) along with 22 penalty minutes. In 29 career NHL games he has earned five goals, two assists and eight minutes in penalties.
The 29-year-old Staubitz played six games for Norfolk this season with 10 minutes in penalties. In 230 career NHL games with San Jose, Minnesota, Montreal and Anaheim, the six-foot-one, 207-pound native of Bright's Grove, Ont., has 10 goals, 11 assists and 520 penalty minutes.
Blacker played five games for the AHL's Toronto Marlies this season, collecting one goal and four penalty minutes. He was selected 58th overall by the Leafs in the 2009 Entry Draft.
