The Canadiens filed a one-year, $5.25 million offer through arbitration, while Subban's camp is asking for $8.5 million.
While though numbers have been strategically presented in the event the two sides cannot agree to a deal and arbitration is the last resort, it's believed the Canadiens are hoping to sign Subban to a long-term deal worth between $6.5 million to $7 million, per season.
Subban's camp is believed to be looking at between $7.5 million and $8 million, per year, on a long-term contract.
Both parties appear set on a long-term commitment -- seven or eight years, a source confirmed -- but the barrier currently revolves around Subban's annual salary.
Subban finished the 2013-14 season with a career-high 43 assists and 53 points, as well as 153 hits.
Drafted by the Habs in the second-round (43rd overall) of the 2007 NHL Entry Draft, Subban captured the Norris Trophy as the NHL's top defenseman in 2012-13 and won a gold medal at the 2014 Winter Olympics with Canada.
