"Oil and gas are clearly fundamental to Alberta's economy and to Canada's but also to Ontario's — and I want everyone to know that I understand that and I want to advance that," Wynne told a corporate crowd in Calgary on Friday.
"Many of our Ontario manufacturers now directly support your industry. I want us to build on that relationship."
Wynne set a different tone than that of her predecessor on her first official visit to Alberta since she became premier of Canada's most populous province in January.
Dalton McGuinty drew Alberta's scorn last year when he said the oil and gas industry was driving up the loonie and making it more difficult for Ontario manufacturers to export their goods. He later softened his stance.
The debate over oil pipelines is heating up in Ontario. There are two major proposals in the works to ship Alberta crude through the province to eastern refineries and export points.
In her remarks, Wynne acknowledged how important it is to Alberta to get its resources to market — including via Ontario — but stressed the need for strong environmental oversight and First Nations consultation.
At hearings this month, many expressed concern over Enbridge Inc.'s (TSX:ENB) proposal to reverse the flow of its existing Line 9 oil pipeline between southwestern Ontario and Montreal and pump more Alberta crude through it.
TransCanada Corp. (TSX:TRP) is planning a much bigger project to bring more than one million barrels of western crude a day as far east as Saint John, N.B. That proposal involves converting part of its existing Alberta-to-Quebec natural gas mainline and building 1,400 kilometres of new pipe to the East Coast.
Unlike British Columbia, Ontario isn't making demands that it get a slice of the pipelines' economic benefit through royalty revenues or another means, Wynne told reporters after her speech.
In the past, B.C. Premier Christy Clark and Alberta Premier Alison Redford have clashed over that question, though they've since taken a more conciliatory tone. The B.C. and Alberta premiers are to meet in Vancouver next month to discuss oil export projects.
In her speech, Wynne also tackled an issue on which Ontario and Alberta disagree — the formation of a national securities regulator.
Ontario, B.C. and the federal government recently announced plans to co-operate on regulating Canada's investment industry, which Wynne says will make capital markets more efficient and effective.
Alberta and Quebec have opposed any federal efforts to unify Canada's 13 separate securities regulators.
"I respect Alberta's position, but I'd like to see if, as we go forward, we can address those concerns as we move to this single regulator, recognizing both of our provinces' interests."
Wynne also said there's room for provinces to collaborate on improving the Canada Pension Plan so an aging population can support itself in retirement. She would also like to work together on a national strategy to invest in infrastructure.
Earlier Friday, Wynne and Redford met at a Calgary cafe. Redford gave Wynne a tiny pair of cowboy boots and a copy of the children's book "Goodnight Moon" for her newborn grandson.
