Saturday night's storm brought high winds, heavy rain and some power outages as tree limbs fell on power lines in several areas of the city.
It also brought some frustration for the Guelph Police Service as several people decided to call 911 because their power went out.
"We are receiving 911 calls from people advising us their power is out. Please don’t tie up emergency lines for non emergencies.
@GuelphHydro is aware of the outages and working on it," Guelph police tweeted at 8:49 p.m. as the storm rolled through.
Police reported trees down "all over the city," power lines down, power out and traffic lights temporarily disabled because of the outages.
Several outages cut power to thousands of homes, the biggest outage affecting 3,911 homes, Alectra Utilities reported.
Alectra Utilities reported that power had been returned to all areas affected around 12:30 a.m. Sunday, but there was another outage they dealt with on Glasgow Street half an hour later that affected 53 customers.
There were no reports of any injuries.
