COC president Marcel Aubut pledged $37 million Thursday to Own the Podium (OTP) over the next four years.
The contribution between 2013-'16 is a 48 per cent increase from the previous four years, a quadrennial that included the 2010 Vancouver Olympic Games.
The additional funding "allows us to continue to provide critical technical and financial support to athletes and national sport organizations that are poised for podium success," said Anne Merklinger, CEO of Own the Podium.
The funding will go toward summer and winter sport.
Canada won a Winter Games record 14 gold medals in Vancouver, and a total of 18 medals at the 2012 Summer Olympics in London.
The COC's goal for Sochi is to improve on the medal count from 2010, and finish at the top of the table for overall medals.
OTP determines and prioritizes funding for national sport organizations with the aim of delivering more Olympic and Paralympic medals for Canada.
