Yes, certainly these estimates of the direct impact of output in the oil and gas industry don't include the benefits or the jobs created in the years of construction it takes to build these oil sands plants. It doesn't take into account the spinoff jobs in transportation and pipelines. I'm just a little nervous about evaluating the utility of these projects solely on their impact on employment.
I remember I did a counterfactual calculation one day. Because refineries are so capital intensive, I was looking at the question of what happened to employment in Montreal when this refinery closed. Using the input-output models, you can trace through the impacts on employment. What I found was that employment would actually go up if you closed the refineries in Montreal and imported the oil, and you get this rather weird result because you hire more longshoremen, more people working on the docks, to unload the oil than you do from refining it.
That doesn't mean we should go around closing refineries to create jobs—that's not the implication at all—but I find that if you just do a narrow-minded focus on job creation, you can come up with counterintuitive results like that. So I advise against focusing too much on just the job-creation aspects of these projects. Look at the broader question of where value is created.
