Canada is developing its requirements for the In-Service Support (ISS) for the new Canadian Surface Combatant (CSC) class of vessels. Canada intends to engage with Industry to obtain relevant advice and recommendations. This advice may be taken into consideration in the development of future solicitation documentation for the competitive procurement of In-Service Support for the CSC. The intent of this LOI is to identify capable and interested Respondents to participate as members of a joint, Government of Canada and Industry, Canadian Surface Combatant (CSC) In-Service Support (ISS) Working Group (CIWG). Suppliers will self-attest to their suitability for CIWG membership in accordance with Section 8 of the LOI. The CIWG will assist the Government of Canada (GOC) in shaping the requirements of future competitive RFP processes and resulting contracts by providing advice, information and recommendations.
