TORONTO - Ontario's legal aid system will get a $150-million increase in funding over the next four years.

The government is moving to end a legal aid boycott that began with defence lawyers in Toronto and spread to Kingston, Thunder Bay and London.

The lawyers complain they aren't getting enough money to try large, complicated trials such as murders and guns-and-gangs cases.

Attorney General Chris Bentley will announce a new office Tuesday to help lawyers manage the big criminal trials.

Bentley says the goal is to come up with a better approach to funding the large cases.

The large, complicated trials account for only 10 per cent of criminal cases, but about 25 per cent of the legal aid budget.

Bentley will also announce a switch to block funding instead of hourly payments for legal aid lawyers doing routine cases.

There will be two other components to the Bentley's funding announcement Tuesday, dealing with families and legal aid clinics.

The majority of legal aid money actually goes to single mothers who are living below the poverty line.
