This Call When Needed ("CWN") is an invitation by the Saskatchewan Public Safety Agency ("SPSA" or "Agency") to prospective proponents to qualify for the provision of short-term aviation services on a "Call When Needed" basis. 

The SPSA anticipates requiring short-term helicopter/fixed wing aviation services, to aid with wildland fire suppression, crew moves and other efforts as undertaken by the Saskatchewan Public Safety Agency within the Province of Saskatchewan.
