Repair work on the north stand at the Shay has now been completed and it has increased the ground capacity to over 10,000.
Calderdale Council had pledged to carry out repairs as part of its successful bid to win a Rugby League World Cup fixture.
Italy will play Tonga at the Shay on November 10 and hopefully be watched by a sell-out crowd and millions on television.
Terracing has been repaired and toilet facilities have been increased and modernised to meet the necessary standards.
Council director Robin Tuddenham, said: “Having two standing terraces behind the goal will help create a great atmosphere at future games.
“The stand has boosted the stadium’s capacity to over 10,300.
“This gives a real opportunity to host more national finals and iconic events like the Rugby League World Cup in November – a massive boost to the local economy.”
Normally, league games for FC Halifax Town and Halifax RLFC attract crowds which can easily be accommodated in two or three stands and to save stewarding costs all four sides aren’t open unless a bumper crowd is expected.
The Rugby League World Cup 2013 kicks off on Saturday, October 26, 2013. It will be staged in four countries with matches played in England, Wales, Ireland and France, with the final on Saturday November 30, 2013.
The competition’s structure will consist of two groups of four and two groups of three.
England are drawn alongside arch rivals Australia, Fiji and Ireland in Group A. Scotland face Tonga and Italy in Group C.
Current champions New Zealand are in Group B.
