The McGill University Health Centre said Tuesday evening that the computer network issues it experienced earlier in the day have been resolved.

The MUHC posted to social media around 6 p.m. a message saying that operations were back to normal. The hospital network thanked people for their patience.

The cause of the network problems was a Hydro-Québec outage in Montreal's Notre-Dame-de-Grâce district Tuesday morning. A spokesperson for Hydro-Québec, Marie Maugin, said the cause might have been a squirrel that touched a circuit breaker.

Electricity was restored after about half an hour.
