"These are the games we have deliver more," Canucks captain Henrik Sedin said. "We were up 3-2. We were playing an OK game. We have to be able to finish it off."
Stecher scored his first goal of the season from a sharp angle 4:31 into the first period to give Vancouver a 1-0 lead, but Los Angeles scored two goals one minute apart later in the period.
Gaborik set up Toffoli to tie the game 1-1 at 13:04, driving the net wide behind the defense and getting Markstrom to commit to the ice before passing to Toffoli in the slot.
Gaborik then scored on a power play, driving to the net off the rush and deflecting Trevor Lewis' centering pass at 14:04 to give the Kings a 2-1 lead.
Goldobin tied it 2-2 on a solo rush, beating Doughty with a nice move into the middle and Quick with a backhand from the slot.
"Great players have a short memory," Kings coach John Stevens said of Doughty. "Not very often that happens. I wouldn't expect to see it again for a while."
