York finished with 103 total points to claim their first title since 1984. Guelph, the CIS men's champions, finished second with 97 points while the Windsor Lancers earned bronze with 81 points.
The Lions now have three men's team titles in program history, following back-to-back wins in the 1983 and 1984 seasons. York coach Colin Inglis was named men's coach of the year following the championship.
With 96 points, the Gryphons claimed their second women's team title in program history. The Toronto Varsity Blues finished second with 93, while Trinity Western finished was with 64.
"It was a great weekend, right from Day 1 to Day 3," said Guelph coach Dave Scott-Thomas, who was named women's coach of the year. "Even though the final team standings came down to the results of the 4x400m, which is great because it's an exciting event, we had done the math and knew that if we performed well in that event, we would win the title."
York swept the male and female outstanding athletes of the meet awards. Dontae Richards-Kwok won the men's award after winning the 60-metre and 300-metre races and helping the Lions to gold medals in the 4x200 and 4x400 relays.
Khamica Bingham took the women's award with gold medals in the 60, 300 and the 4x200 relay. She set a CIS record in the 60 with a time of 7.26 seconds.
"I'm happy I was able to finish my career at York with a team title," said Richards-Kwok. "It came down to that last race, the 4x400, and I knew if I got the baton at the right time, I could do what I needed to do to help us get that title."
Trinity's Emma Nuttall broke the CIS championship meet record in the high jump, with a leap of 1.88 metres. The previous record of 1.87 was set by UBC's Tammy Lutz in 1986.
"It was such a relief," said Scotland's Nuttall. "I knew I had that jump in me. I really wanted to come in here this weekend, win gold and set the record. I wanted it at the Canada West championships, but it wasn't meant to be then. It was a wee bit nerve-wracking, but once I got the support of the crowd tonight, I really fed off that energy, and I knew I could make the jump."
Ottawa's Sekou Kaba also set a record in the men's 60m hurdles.
