The Ontario Medical Association says it's applying to the Ontario Superior Court of Justice for a review of the government's negotiating tactics and its unilateral fee cuts.
The OMA walked away from talks after the province cut $340 million worth of fees for doctors' services, and says it won't return without a conciliator.
Health Minister Deb Matthews says that's not the real issue.
Matthews says what the doctors really want is more money for their salaries, something she insists the province simply can't afford.
The OMA says the government has not negotiated in good faith, and wants the court to reverse the fee cuts.
The opposition parties say the government should have seen the lawsuit coming, and should return to talks with the doctors.
The organization that represents 25,000 Ontario physicians says the government's demand for a two-year wage freeze amounts to a pay cut for doctors.
