The fair market wage is determined by the same market forces of supply and demand. If they can't find local workers at the wage they are offering, raise the wage until they can. If they can't afford the wages necessary to staff their business with local employees and still make a profit, then they have failed as a business. Simple as that.

Temporary foreign workers are supposed to fill skill gaps in the economy when not enough qualified workers exist, not to supply cheap labour when employers want to improve their bottom line.

I'd also like to point out that smaller local businesses don't have the power and money to exploit temporary foreign workers in the way corporations such as Tim Hortons can, putting them at a severe disadvantage to compete with them. These businesses still manage to survive in most markets, but would grow and thrive if the playing field was leveled. Fuck corporations, support small local businesses.
