It's the Goldilocks story of provincial politics: one opposition party says the Liberals' public sector wage freeze proposal is too tough, the other says it's not  tough enough.

Tuesday is the deadline for opposition parties to submit their ideas to the finance minister.

NDP leader Andrea Horwath wrote a letter to Dwight Duncan, suggesting to throw out plans for what she calls "simplistic and unconstitutional legislation." She goes on to say the government needs to work hard to get agreements with unions, underlining it needs to negotiate.

Horwath says the NDP can't support the proposed legislation.

Meantime, PC Economic Development Critic Monte McNaughton continues to repeat the Tories want both an across the board public sector wage freeze and to reduce the size of the public sector.

Despite all this, the Premier says he believes the province can work something out, pointing to various sections of the public sector that have already agreed to freeze salaries for two years.
