Ontario's governing Liberals say they will clamp down on corporate tax compliance, work with public sector workers on wage talks, and give local residents more say in whether they get a wind farm, gas plant or casino. It's among the many promises they're making in the throne speech today, which marks the start of the legislative session. It's also Premier Kathleen Wynne's first major test, as she'll have to convince at least one of the opposition parties to support the speech to avoid triggering an election. The Liberals say they want to work with the opposition parties, the private sector and non-profits to find ways to improve the economy, create jobs and slay the deficit. The speech promises to restrain spending to one per cent below gross domestic product once the budget is balanced in 2017-18. But they also plan to "evaluate corporate tax compliance,'' while exploring a tax break by raising the exemption threshold of the Employer Health Tax.
