Harper also told reporters that while lower prices would have a significant impact on oil-producing provinces, consumers would enjoy the benefit.

Benchmark prices for crude have halved over the past six months, posing a particular challenge for oil producers.

"As rapid a negative a change that this is for the industry, the industry, even in my lifetime, has lived through changes this extreme and more on many occasions," Harper told reporters during an event in British Columbia.

"This not without precedent. It's a resilient industry and it will see its way clear to a prosperous future," he said.

ARC Resources Ltd on Wednesday became the latest in a string of Canadian producers to cut their budgets in reaction to the drop in prices.
