Just after 5 a.m. PT, mud rushed down the side of a steep slope and crossed a rural stretch of the 7700 block of 264th Street, moving a cement barrier.
The slide also covered the side of a home below the road. No one was injured and there was only minor damage to the house.
About 100 metres of 264th Street has been closed for much of the morning. It's not clear when the road might reopen.
While officials were cleaning up the first slide, officials confirmed they were responding to reports of a second landslide in the municipality, this time at 252A Street and 72nd Avenue.
The second slide was much smaller and did not affect any roads or homes, city officials said.
City officials say small mudslides on the hills into Glen Valley are common this time of year.
A rainfall warning is in effect in the area with between 10 and 20 millimetres expected to fall throughout the day.
