CSN Chicago's Blackhawks Talk noted the 57-year-old coach is now under contract through the 2019-20 campaign.
Quenneville has established himself as one of the league's most valuable coaches while guiding the Hawks to three Stanley Cup titles over the past six years. His record across 580 regular-season games in charge of the franchise is 343-168-69 with an additional 73-44 mark in postseason play.
Having the likes of Patrick Kane, Jonathan Toews and Duncan Keith obviously helps the cause, but he's found a way to translate that talent into consistent titles. That's not as easy as it sounds, as franchises like the Pittsburgh Penguins and Washington Capitals can attest.
The Blackhawks have seen several players from last year's championship team, including Patrick Sharp, Brandon Saad and Johnny Oduya, leave during the offseason as they juggle cap issues. They still manage to own the league's third-highest point total just after the halfway point.
That continued success warrants the extension for Quenneville. Its announcement comes on what could be a special day, as noted by Mike Zeisberger of the Toronto Sun:

#hawks Joel Quenneville can tie Al Arbour for 2nd on #nhl's all-time coaching wins list tonight. His reward: 3-yr extension. Well deserved2016-1-12 16:42:06
Chicago is set to face off with the Nashville Predators on Tuesday night. Tying Al Arbour would be a terrific accomplishment, but Quenneville would still be 462 regular-season victories and six Stanley Cups behind Scotty Bowman, the all-time leader in both categories.
Locking him in now made sense for both sides as the Hawks will soon turn their focus to what they hope becomes another deep playoff run.
