He won't officially become Vancouver's new mayor until next month.

But Gregor Robertson is already working on his new vision for City hall. Solving homelessness is supposed to be one of his top priorities. But first he will have to deal with the growing controversy over a loan to the developer of the Olympic athlete's village.

On Monday, Robertson promised to set the record straight on the controversial loan that critics say has diverted attention away from some of the real challenge that the new mayor will face.

"We'll be working with the city manager on trying to bring some clarity to that situation and more importantly to be looking at a public council meeting on the $100 million Olympic loan and making sure we can set the record straight on that," said Robertson.

The promised came after city hall confirmed its chief financial officer Estelle Lo has resigned.

Lo has been silent and on vacation since word broke last month of the $100 million loan guarantee to the Olympic Village developer. Despite reports she had actually quit in protest weeks ago, officials insist she only resigned this on Monday morning.

City of Vancouver spokesman Kevin Ramsay declined to say what led to Lo's resignation. "That's a personnel matter and a personal matter that we're not going to discuss," he said.

Since the city wouldn't answer that question, CTV News went to Estelle Lo's apartment to ask for an explanation. But a CTV reporter got no answer.
