OTTAWA — To help mitigate the spread of coronavirus, local hospitals have banned all unessential visitors — including expecting fathers. Now, the Ottawa Hospital is experimenting with curbside pickup of newborn babies. “It’s really convenient,” said Edward Ashburn, who just became a first-time father. “I didn’t even have to get out of the car; the guy just put junior in the trunk, and I was good to go. Plus, you don’t have to tip.”
