Miah-Marie Langlois scored a game-high 20 points as the top-seeded Lancers defeated the No. 5 Fraser Valley Cascades 65-45 in a semifinal Saturday.
Windsor plays its fifth straight CIS final Sunday against the No. 2 Saint Mary's Huskies.
Saint Mary's advanced with a 67-54 victory against the No. 3 Saskatchewan Huskies.
The defending champs had to grind it out against Fraser Valley as they trailed 25-24 at halftime after shooting only 19.4 per cent from the floor in the first 20 minutes.
"We played them twice earlier this season so we knew they were a good team. We weren't surprised at all they gave us a good battle," said Windsor guard Jocelyn LaRocque, referring to 27 and 20-point non-conference wins in late December.
"We weren't too worried about shots not dropping. We were just saying as a group keep shooting, and if they don't go in, we'll just rebound like crazy. We knew if we kept shooting at some point they were going to drop."
Jessica Clemencon scored 15 of her 20 points in the second half and picked up nine rebounds while Korissa Williams brought down a team-high 11 boards in the win for Windsor.
Nicole Wierks had a team-high 17 points for Fraser Valley while her sister Sarah led UFV with 11 rebounds on the night.
In the first semifinal, two-time CIS player of the year Justine Colley dominated with 38 points for the Huskies, who trailed 23-20 after the first quarter.
But Saint Mary's pulled away with a 21-9 third quarter and only needed to shut the door in the fourth.
Dalyce Emmerson led Saskatchewan with 23 points and 12 rebounds.
