Burnaby Lake had its four-game winning streak snapped at home by Capilano RFC on Saturday.
Less than a month earlier, Burnaby Lake stunned the defending Lower Mainland champs 25-0 at Klahanie Park, but it was the North Shore side that got the better in the rematch at Burnaby Lake-East on Saturday.
Capilano defeated the host Lakers 28-8 to move to 5-1 in premier division play. Burnaby Lake dropped to 4-1 with the loss.
In other premier league games, James Bay Athletic Club also improved to 5-1 following a 16-10 win over the Vancouver Meraloma.
The Victoria club scored all its points in the opening half, including the team's only try from former Canadian international Dave Moonlight.
Canadian sevens national team player Connor Braid booted three penalties for James Bay.
Castaway Wanderers scored eight tries to move to 4-1-1 with a 36-17 won over winless Abbotsford.
The UBC Old Boys squeaked by the University of Victoria 26-25.
Burnaby Lake is on the Island next Saturday with a rematch against UVic.
