Generally, disruptions to all of your services, such as during a power outage or during a labour dispute, do not require this special notice. However, if the disruption has a significant impact on people with disabilities, you should provide notice of the disruption of service. In Ontario, under the Accessibility Standards for Customer Service, as of January 1, 2012, organizations are required to publicly notify customers of temporary disruptions of services or facilities or if they are expected to be temporarily unavailable in the near future, including the steps to take to access alternative methods.
