Nixon, who worked so hard in the summer to save the club, said: "What Gary and the players have done is nothing short of magnificent.
"Don't forget this club could easily have gone out of business and then everyone had to refocus all over again after being demoted from the First Division. The way they reacted to all that has been fantastic, and at times they have been mesmerising to watch."
Livi have won the title barring a meltdown. Forfar can only draw level on points now by winning their remaining four games and they would have to make up a difference of 17 goals, while Livi would have to lose all their games.
The game was nip and tuck until Stevie Tosh converted a penalty in the 71st minute, however, former Hibee Damon Gray hit an equaliser four minutes later when he accepted a David Greenhill lay-off to dampen the celebrations of the travelling Lions fans.
Gray came closest to opening the scoring in the first-half when his shot was cleared off the line by defender Jason Talbot. Tosh also saw a shot fly just wide of an upright and Berwick's Paul Currie blazed his strike over the crossbar.
Livi also suffered a scare when goalkeeper Roddy McKenzie was injured late on in the first-half.
After the break, Berwick almost broke the deadlock when a Greenhill 30-yard howitzer pinged back off the bar.
Bollan said: "Our first-half performance was not up to scratch."
