Halifax took control in the race for the Qualifiers with a nervy 16-8 win at top four rivals Toulouse Olympique.
Clement Boyer crossed to give the hosts an early lead against his former side but Steve Tyrer levelled the game less than five minutes later.
That was how it remained until five minutes before the close of a tight half as Adam Tangata scooted over for ‘Fax.
Tyrer knocked over a penalty goal after the break but Mark Kheirallah raced over to cut the deficit to two points.
However Ben Johnston sealed the most precious of wins with five minutes remaining before Bastien Canet was sinbinned for Toulouse, who fall two points adrift of fourth-placed ‘Fax.
