The University of Toronto Varsity Blues men's and women's curling teams advance to the semifinals as Day 4 of the OUA championships wrapped up Sunday night at Guelph Curling Club.

In men's action, the two-time defending champions from Waterloo were beaten by the upstart Toronto Varsity Blues in a suspenseful quarter-final contest on Sunday night. After the Blues forced an extra end with two points in the eighth, skip Evan Lilly froze his final rock near the button, putting the pressure on the Warriors' Jake Walker to stick his last shot. Walker's final stone slid just past the button, allowing the Blues to steal a point and a berth in the semi-finals against Brock, who topped the 2013 CIS Champions earlier in the day and took top spot in Pool A. 

On the women's side, Toronto solidified its place in Monday's semi-finals with a 6-1 record to win Pool A. The Blues will take on the Carleton Ravens, who defeated Laurentian by one point in quarter-final action, in the semifinals on Monday morning.

The women's and men's semi-final games all start at 9:30 a.m. on Monday morning at the Guelph Curling Club. The gold-medal matches and bronze-medal contests begin at 1:00 p.m. The top three teams from the women's and men's competition all book spots in the CIS national championships taking place at the University of Regina from March 19-23.
