Yukon Premier Darrell Pasloski is promising tax cuts for business and record spending on roads and buildings in Tuesday's budget, but business leaders are withholding their cheers until they hear details.

Pasloski revealed some of the budget highlights Friday at a Yukon Chamber of Commerce lunch meeting, saying the 2014-2015 budget will include the largest capital investment in Yukon's history.

But despite promises of record spending and tax cuts for business owners, the crowd didn't seem overly enthusiastic. Some in the audience, such as mining consultant Kevin Brewer, say they still have unanswered questions about things like mine permitting.

"We still have a lot of concerns in those areas and we haven't been well informed to date."

Renewable energy consultant John Maissan said he would like to have heard more about the environment.

"Overall there was very limited amount of information on climate change and the need to address not just our electricity consumption but also the energy we use in heating our homes and our transportation," he said.

Pasloski says some questions may just have to wait until he delivers the budget speech Tuesday afternoon in the Yukon legislature.
