TORONTO - Once-troubled eHealth Ontario will unveil a $72-million plan Wednesday to create a single electronic health records system in the Toronto area.

The ConnectingGTA system would link 700 health providers from 43 Toronto-area hospitals and 201 nursing homes, which government officials say will improve patient care for nearly half of Ontario residents.

The first phase of the project will be completed in 2013.

EHealth, which was mired in controversy two years ago, has been tasked with creating electronic health records for all by 2015.

The scandal, which included lucrative untendered contracts and lavish expense account abuses, saw $1 billion spent over a decade to develop electronic health records but with very little to show for it.

It forced the resignation of a health minister, the agency's CEO and other key players.
