911 service down across Ontario and parts of Canada

911 service went down across parts of Canada, including in Ontario (Toronto, Waterloo), and possibly other provinces like Nova Scotia. Emergency responders reported disruptions on social media and urged residents to use non-emergency lines instead. The outages affected multiple police services such as those in Toronto, Ottawa, London, Ontario, and elsewhere. A spokesperson for Montreal police indicated that the issue stemmed from a telephone carrier responsible for 911, potentially causing calls to be rerouted nationally. Most areas reported resolution by around 7:30 a.m. ET.
