District of North Vancouver Fire and Rescue Services responded to the area of Fromme Road and Hastings Creek where water began flooding roads and flowing into Argyle Secondary School sometime before 10:30 p.m. PT.
Residents reported seeing about 15 centimetres of water running down Fromme, as fire crews and police officers went door to door where water was running down into people's garages.
As of Tuesday morning, crews in North Vancouver have closed Fromme Road and set up cinder blocks to stop houses flooding.
Argyle Secondary School suffered substantial flood damage and will be closed for the day.
Deep Cove businesses flooded
On Gallant Avenue in Deep Cove, another creek backed up and flooded local businesses, including the Arms Reach Bistro.
Seymour art gallery and Deep Cove theatre volunteer Michael Smith said he has been bailing water since 3 a.m. - but it could be a lot worse.
The flooding was confined to one side of Gallant Avenue however, and the area's famous Honey's Donuts still opened for customers on Tuesday.
Kilmer Creek also burst its banks, raising fears of boulders flowing into local streets. Residents' homes were already flooded, described as gushing with water, by the time they were evacuated.
The West Vancouver Fire Department was also busy Monday night, responding to multiple calls of flooding in homes and reports of local flooding on streets in the Dundarave area.
