MONTREAL—  Transcontinental says about up to  1,600 temporarily laid-off staff have brought back in the last several weeks.The company says a gradual recovery in printing volumes has allowed it to recall more than one third of the employees laid off because  of COVID-19. "Obviously, things are improving as many businesses are back to business, they're back advertising," chief financial officer Donald LeCavalier said in a conference call . LeCavalier doesn't think the printing business will fully recover by early fall but could reach 80 per cent by that time if there isn't a second wave of infections. Many retail customers that remained open during the crisis used flyers to communicate COVID-related information and to help build brand loyalty, said chief executive Francois Olivier.
