If I may, I'd like to give you an idea.
Let's say the cost of the tax credit is $60 million. Since this amount represents 20% of eligible expenditures, we can assume that expenditures will be approximately $300 million. If we add a few ineligible expenses, the total amount is $350 million a year in rehabilitation expenses. We can assume that at least two-thirds of this amount, or $200 million, are labour costs. The big question is whether the $200 million would have been spent without the tax credit. This is also what the Department of Finance told you last week.
To answer the question, we would have to know what the expenses in addition to the tax credit would be, expenses that would not otherwise have occurred. If the tax credit did not exist, that money might be spent elsewhere in the economy and it would still generate jobs in other sectors.
