Ian McCall's in-form side sealed a return to the Championship in style with a five-goal show against the Bairns, who drop to fourth place.
Zak Rudden, Scott Tiffoney and Brian Graham were all on target in the first half, with Graham and Joe Cardle netting after the break.
The Jags, who are four points clear of closest challengers Cove Rangers, don't play this Saturday and complete their League 1 campaign at Montrose on Tuesday.
