Tonight on Global National: Ventilation systems in Canada's schools are the latest safety concern as the new school year quickly approaches amid the coronavirus pandemic. Heather Yourex-West explains why educators are especially worried about older buildings and colder weather. Plus, students in B.C. will return to school two days after their teachers, since the provincial government announced it's delaying the start of the new school year.

Catherine Urquhart explains the decision and the rules on face masks.
Meanwhile in New Zealand, after going more than 100 days without any community transmission of the coronavirus, Auckland, the country's largest city, is going into lockdown due to a new COVID-19 outbreak. As Crystal Goomansingh explains, the source of the new outbreak has baffled health officials.

Turning to political news, presumptive Democratic presidential nominee Joe Biden made his first appearance with running mate Sen. Kamala Harris, who could become America's first Black and female vice-president come November. As Jennifer Johnson reports, President Donald Trump is already taking shots at Harris. With 12 weeks to go until the U.S. 2020 presidential election, Americans are getting the third opportunity to elect their country's first female vice-president. Eric Sorensen explains why Harris has a chance of making history.

And in Canada, Bloc Québécois Leader Yves-François Blanchet is calling for a fall election unless Prime Minister Justin Trudeau, his chief of staff Katie Telford and Finance Minister Bill Morneau resign. Mercedes Stephenson explains why, and the likelihood of it happening.
