Lisa Forrest headed Glasgow City three up with the first goal of her hat-trick
Rangers missed the opportunity to win the SWPL title as Glasgow City put six past Leanne Crichton's side.
Hearts' 2-0 defeat by rivals Hibernian meant a win for Rangers would have seen them leapfrog the Jambos at the top, but they were outclassed at Petershill Park.
Lana Golob put City in front on 10 minutes before a Hayley Lauder volley and a Lisa Forrest header made it 3-0 at half-time.
Forest fired in her second as another corner caused havoc in the Rangers box and things went from bad to worse for the visitors when Emily Whelan found the bottom corner from the edge of the box.
There was still time for Forrest to complete her hat-trick with a fine glancing header on a dominant afternoon for Leanne Ross' outfit.
City finish third in the table, two points behind Rangers and four behind champions Hearts.
