More than 40 organisations spanning "all sectors" of the global sports industry have joined the new independent alliance, which is seeking to "drive forward key reforms across good governance and integrity".
SIGA was formally launched last week and has already received support from the Trinidad and Tobago Olympic Committee (TTOC).
It follows a resolution to take specific measures to honour good governance at last year's CANOC General Assembly in Paramaribo in Suriname.
“The CANOC Board fully recognises the severe threat impacting the purity and virtue of sport," said the body's chairman, Steve Stoute.
"One of CANOC’s mandates is to promote the highest standards of good governance among our membership and CANOC will be motivating all of our member NOCs to become signatories to the Statement of Intent.
"This will be tabled at the Annual General Assembly in October."
Caribbean officials have been at the centre of many governance scandals in football in recent years.
Cayman Island's FIFA vice-present Jeffrey Webb among those arrested by Swiss police acting at the request of the United States Department of Justice on charges of racketeering, wire fraud and money laundering conspiracy during last year's FIFA Congress in Zurich.
Another former FIFA vice-president, Trinidad and Tobago's Jack Warner, was also banned for life from taking part in football-related activity in 2015 after he was found to be a "key player" in illegal money making schemes.
This bad reputation of the regions ethics make it particularly important to take specific action to bring about improvement, CANOC officials believe.
“We thank the team from SIGA for travelling to the Caribbean to facilitate this action and interface with the CANOC Board," added Stoute.
"We pledged to work closely with SIGA in efforts to achieve the proposed goals.”
