The 2016 Renwick Cup is the men's Senior "AAA" championship for the province of Ontario. The tournament was scheduled to be held on April 1 to April 3, 2015 at the Kenora Recreation Centre and will match up the independent Kenora Thistles (affiliated with Hockey Northwestern Ontario) and the 2016 Allan Cup Hockey playoff champions (affiliated with the Ontario Hockey Federation) in a best-of-three series to determine the region's participant in the 2016 Allan Cup being held at the T.G. Smith Centre in Steinbach, Manitoba, April 11-16, 2016.The Kenora Thistles announced they were ceasing operations on January 10, 2016. This means the Allan Cup Hockey playoff champion will now directly advance to the 2016 Allan Cup as the regions representative.
Traditionally the Senior "AAA" champions of Hockey Northwestern Ontario, Northern Ontario Hockey Association and the Ontario Hockey Federation have competed for the Renwick Cup but HNO has been reduced to one team, the NOHA has not had any teams and the only members in the OHF are members of Allan Cup Hockey.
