2008-09: Chosen in the first round, 1st overall, of the 2009 QMJHL Entry Draft by the Val d'Or Foreurs.
2009-10: In his QMJHL rookie season, Archambault played in 58 games for the Foreurs. He scored 12 goals and chipped in 15 assists for 27 points. Archambault registered no points in 4 playoff games. Archambault played for Team Quebec at the World U-17 Hockey Challenge, scoring 3 goals and adding 4 assists for 7 points in 5 games.
2010-11: In 65 games for the Foeurs, Archambault scored 20 goals and added 33 assists for 53 points. In 4 playoff games, Archambault scored 1 goal and chipped in 2 assists for 3 points.
2011-12: Archambault had a difficult third season in the QJMHL adjusting to a new team, the Voltigeurs and was sidelined for most of the second half of the season with an upper body injury (concussion). He scored 17 goals (two on the power play) along with 22 assists and a poor minus 17 rating in only 45 games. Archambault and his Drummondville team were clearly out played while being swept 4-0 in their first round QJMHL playoff series against the Quebec Remparts. The offensively skilled winger scored one goal along with two assists and a poor minus four rating while taking just five shots and only getting two on the net.
Despite his smaller size, Archambault has excellent speed, acceleration and very quick hands but needs to use his teammates more often in order to create more scoring chances. The offensively talented winger has good creativity, hockey sense but has a tendency to hang on to the puck too long and fails to take advantage of good scoring opportunities. He will need to add more strength and size while improving his willingness to work in the defensive zone.
Archambault will be expected to bring more offensive punch to the Voltigeurs in his fourth QJMHL season while improving his defensive play away from the puck. He will need a good year in order to receive an entry level contract from the Canadiens.
