OC Transpo says the O-Train is temporarily offline due to power outages caused by a severe thunderstorm that swept Ottawa.
The storm brought heavy rainfall and very strong winds, with gusts of up to 120 km/h at some point in the afternoon.
More than 100,000 Hydro Ottawa customers were knocked out by the storm.
OC Transpo says the O-Train Line 1 will be replaced until further notice with R1 bus service between Blair and Tunney’s Pasture stations.
The OC Transpo website was also taken offline.
