The opposition Liberals and NDP say the plan unveiled Tuesday is lacking in details even though the system is supposed to be operating by the end of 2014.
Liberal Eddie Joyce says there's no legislation in place, no commitment on call centres and no clear plan on how the system will be paid for.
NDP member George Murphy says the government is taking baby steps even though the province is far behind other jurisdictions when it comes to co-ordinating emergency calls.
The government says residents will pay less than a dollar a month for the service.
It says a team will develop draft legislation, create a set of guidelines and make arrangements with call centres.
Just 40 per cent of the province is covered by 9-1-1.
