Crewe already had George Ray and Liam Nolan called up for Wales and Northern Ireland U-21's respectively prior to the game against Notts County.
Along with Billy Waters who was on standby for the Welsh U-21 team it was the call up of Marcus Haber to the Canadian squad that meant that the Railwaymen request to the Football League for a postponment was granted.
No new date has been arranged between the two clubs.
