It isn't easy finding a parking spot at the Calgary headquarters of DIRTT Environmental Services.

Cars are double parked outside the manufacturing company's southeast Calgary offices, while inside workers race to meet the growing demand for the custom building interiors fabricated there.

For DIRTT's president Scott Jenkins, thoughts of an economic downturn couldn't be further away.

"I think we are a great testament to the strength of the economy in this city and — yes — there are challenges right now, but there are companies like us that are thriving."

Jenkins has watched the company's sales grow from about $20,000,000 a decade ago to around $240,000,000 this year.

"We are a technology company, in manufacturing, based in Calgary and we are growing rapidly."

It's a tenfold increase that has occurred amid two downturns in the local energy industry.

7% of Albertans work in oil and gas

University of Calgary professor Trevor Tombe isn't surprised. The economist says only about seven per cent of Albertans work in the oil and gas sector — a number that he says surprises many.

"We have a fairly diverse workforce, the most diverse in the country in terms of how evenly employment shares are spread across sectors."

Tombe points out that oil and gas and mining combined accounted for just 175,000 jobs in Alberta last year, the fifth largest sector behind construction, health care and retail.

Here is a look at how many people work in the top 10 sectors of Alberta's economy:

Construction: 256,000

256,000 Health care: 241,000

241,000 Retail trade: 234,000

234,000 Professional scientific and technical services: 184,000

184,000 Oil and gas and mining: 175,000

175,000 Accommodation and food services: 150,000

150,000 Manufacturing: 145,000

145,000 Transportation and warehousing: 130,000

130,000 Education: 125,000

125,000 Other services: 122,000

Unemployment below national average

Tombe says that diversity of employment is why Alberta's economy has fared relatively well, despite the downturn in the energy industry.

"Even now, the economy as a whole, the unemployment rate is below the national average, the number of new job vacancies relative to the number of workers who are unemployed is better than the national average."

Despite those facts, Tombe says, the perception among many is that the oil and gas sector is far more important to the province's economy than it actually is.

"A lot of the bad news that people focus on is concentrated on that one sector, and they neglect that a lot of other sectors are hiring."

And it's not just the manufacturing sector that is faring reasonably well during the latest downturn in the energy industry.

Tourism boost

Tourism Calgary's Cassandra McAuley says that, like the manufacturing sector, her industry is prospering during the slowdown, in large part due to a low Canadian dollar,

"The dollar certainly is favourable for people either looking to stay home and do kind of a 'staycation' or for Americans looking to come up and explore what we have," she said.

Those are the precise conditions that have led to a record year at the Calgary Zoo, according to its senior director of corporate services and customer experience.

"We have been surprised by the resiliency. We are actually on track to have the third best year in our history; we are going to sell a record number of memberships this year," said Lindsey Galloway.

Country's most diverse staffing

For Tombe, the fact that many parts of Alberta's economy continue to fire on all cylinders is proof that the province's economy is diversified.

He adds, however, there is a reason that downturns in the energy industry feel so significant in Alberta.

Unemployment remains below the national average, and despite tens of thousands of layoffs in the oil and gas sector there are still jobs to be had. (Erin Collins/CBC)

"The primary issue in this province around diversification is government revenue, so a good fraction of it comes from royalties, and when oil prices fall it presents a huge challenge to the government budget."

It's a problem with a simple economic fix, according to Tombe — implement a provincial sales tax to decrease the government's reliance on funds from energy royalties.
