Willowbrook Shopping Centre was briefly evacuated on Tuesday morning, March 29, after a gas leak nearby.
The leak was caused by damage to a gas line by a third party, said Fortis spokesperson Jas Baweja.
The leak started around 10:40 a.m., and while crews were on scene within about five minutes, it required the mall to be evacuated until 12:50 p.m.
Baweja said the gas leak was under control after that, but there is no estimate as of Tuesday on how long repairs will take.
A number of businesses in the area have been impacted by the loss of natural gas due to the leak.
