Cheshire West and Chester leader Louise Gittins, chairman of the committee, also responded to questions from a union on the size of the proposed combined authority and any impact on the police and fire services in the area.
The government’s devolution white paper had expected strategic authorities to have a population of about 1.5 million or more, and local authorities to each have a population of 500,000.
All three authorities have a population below 500,000 and their combined population is about 990,000.
Ms Gittins said the size would not affect the area.
“Our devolution deal, because of the importance of what we have to offer, we have flexibility,” she said.
She added that the councils had “no ambitions to change any boundaries” such as health, fire or police.
