MONTREAL — Several hundred construction workers at Montreal's superhospital downed tools for part of the day Wednesday because of the heat.
They said there was not enough ventilation in the downtown building to allow them to stay on the premises.
One worker said it was 35 C inside with hardly any air circulating.
A union spokesman said at least three people had to be treated for heat stroke.
Most of the workers returned to the job later in the day.
