Damage is pegged at between $50,000-$75,000 after flooding at the Downtown Mission in Windsor.
The intense rain Thursday morning caused flooding in the basement of the mission's Wellness Centre at 875 Ouellette Ave.
It created problems with the building's elevator and the mission's 103 bed Sanctuary Program was affected.
Five guests had to sleep on mats in the hallway.
"We accommodated the guests who couldn't go up the stairs, they slept on a mat in the hallway of our building at 875 Ouellette," says Ron Dunn, executive director of the Downtown Mission.
Speaking on AM800's Lynn Martin Show, Dunn says repairs are underway.
"What I am being told is obviously the city system was overloaded and the water had nowhere to go so it would go to the lowest point which unfortunately is our elevator pit."
He says there were 4-6 inches of water covering most of the basement.
The mission purchased the building two years ago and Dunn says this has never happened before.
He is hoping to have repairs done Friday or Saturday.
