According to B.C.'s Ministry of Environment, the incident occured at a gas line that is operated by Enbridge.
"The most significant impact right now is what we are doing in terms of precautions", said B.C. Minister of Energy Michelle Mungall.
There were no injuries and RCMP said Thursday there are no indications the explosion was criminal in nature.
The second pipeline was carefully checked before permission was received to restart it at about 80 per cent of its normal capacity, Enbridge said in a statement.
McTeague said gas prices on Vancouver Island will likely remain inflated for a week or two until the damaged pipeline is repaired.
Northwest Natural, Puget Sound Energy and Northwest Pipe - which normally receive gas from the Enbridge pipeline - were able to reverse the flow back north.
While everyone got out of the area safely, Teegee said it had been a stressful day that had taken an emotional toll.
Although the gasoline you pump into your vehicle is different than the natural gas in the pipelines, the natural gas is used to power oil refineries.
"We don't know what caused this explosion yet but once we do know, no doubt there will be some lessons to be learned and we will be implementing those as regulators".
He said 85 per cent of the gas FortisBC feeds to about one million B.C. customers is carried by the twinned Enbridge pipeline that runs from northern B.C.to the United States border south of Vancouver.
Excess gas in the Okanagan and southeastern B.C. will be routed to the Lower Mainland, Stout said.
"It's really grown in the last four years or so", he said, noting Fortis has told him they have connected more homes in Victoria in the last year to natural gas than in any other year. About 100 people were evacuated from their homes in a nearby Aboriginal community on Tuesday as a precautionary measure.
Associate director Ian Archer of IHS Markit says some B.C. gas is being redirected into Alberta markets, causing prices there to slip from around $2.50 per mcf to just over $2.
