Ontario's finance minister says he has some concerns with the federal budget.

While Charles Sousa points out it focuses on what he earmarked as priorities such as infrastructure, skills training and tax loopholes, there are some things has questions about.

Ottawa's $47 billion investment into infrastructure over ten years is back-loaded, to which Sousa said "the devil is in the details." He says he hopes the province can move forward with it's own plans for transit expansion.

As for skills training, Sousa underlines the control seems to be out of the province's hands but he wants the flexibility to determine how the funding is used. Province's provide one-third of the funding for the $15,000 Canada Jobs Grant.

As for what was left out, Sousa says he wishes the feds addressed better way to crack down on the underground economy.

While Sousa was diplomatic in tone, former Ontario Finance Minister Dwight Duncan took to Twitter to express his concerns.

On transit,  Duncan was much more tweeting the backloaded funding is "not good news for families who need better public transit." He also write "Nothing bold or innovative in the Canada Job Grant. Ontario pioneered with second career."
