A native of Huntsville, Ontario, Ethan Moreau was drafted 14th overall by the Chicago Blackhawks in the 1994 NHL Entry Draft while he was enjoying a fine junior career in the OHL with the Niagara Falls Thunder and a brief stint with the Sudbury Wolves. The young forward was returned to his junior team in 1994-95 then played 71 games for the IHL's Indianapolis Ice in 1995-96.
Following a brief stint with the Hawks in 1995-96, Moreau showed signs of promise by scoring 15 goals, 31 points and registering 123 minutes in penalties in 1996-97, however, his play leveled off after that. Chicago sent him to the Edmonton Oilers late in the 1988-99 season, after only parts of three seasons with the club.
Upon his arrival with the Oilers, Moreau saw increased ice-time and his offensive numbers showed. In 1999-00, he equaled at the time his career high for goals with 17, bettering that total in 2003-04 with 20 and since his arrival has emerged as one of the team leaders.

During the lock out year, Moreau played 16 games for EC Vilacher of the Austria league scoring 16 points in as many games. His return to the NHL in 2005-06 saw the Oilers assistant captain notched 27 points. In the 2006 NHL playoffs, Moreau demonstrated game in game out his dedication and leadership abilities on ice. Moreau and the Cinderella Oilers would take the league by surprise en route to the Stanley Cup Finals. After a hard fought seven-game series however, the Oilers were defeated by the Carolina Hurricanes.
On October 6, 2006 Moreau was re-signed for 4 years by the Edmonton Oilers. However his next two seasons in Edmonton were spent recovering from a pair of injuries. In 2006-07, he missed the majority of the season recovering from a shoulder injury. The following season during training camp, Moreau suffered a fractured left foot. After being named the club's new captain, he would return and compete in 25 games during the 2007-08 season and help stabilize a dynamic young Oilers squad which just barely missed the post-season playoffs.
In 2009, Moreau became the second Oilers player, joining Kevin Lowe (1990), to earn the King Clancy Trophy. The heart-and-soul of the Oilers hockey club, one of Moreau's main focuses off the ice has been to take a lead role in the Edmonton Oilers Community Foundation and in particular the Inner City High School project. Personally volunteering to be the spokesperson for the initiative, Moreau is helping to raise funds for the daunting task of building a new facility that will accommodate 150 students, more than a 125% increase over the current building, thus allowing troubled youth a top quality educational environment and residence. He has also led the charge in the dressing room for the "Caps for Cancer" and "For Puck Surprise" programs, which raised more than $300,000 combined for local charities. Moreau's commitment to his community also includes work with the Cystic Fibrosis Foundation, Canadian Cancer Foundation and the United Way, along with regular visits to the Youth Emergency Shelter and Stollery Children's Hospital.
