Jim Hamilton grabs the first goal in his second spell at Almondvale to compliment Robbie Winters' earlier strike, but an injury time Loons score sees the game end in a draw.
Livi looked to be on easy street when Winters opened their account on 55 minutes, closely followed by Jim Hamilton doubling the lead from inside the box.
But Ross Campbell pulled a goal back with a low shot just three minutes later.
Forfar's Kevin Fotheringham was sent off for a second bookable offence a minute from time, but Stephen Tulloch sickened the visitors with a late equaliser, capitalising on a blunder by Lions keeper McKenzie.
