I was working in Toronto for a local delivery company, doing drops of large cans of printing ink at various locations. AM 1010 ran a FLASH message at a few minutes after nine AM. BY 930, the Toronto Fire Department and the Toronto Police Service had both made TV and radio announcements that any of their members who were on "days off " could head to NYC, to help. Dozens of ordinary Canadians did the same thing, driving to the border, and into NYC, or New Jersey.
Taylor Parnaby, the AM 1010 news director got in his car in Toronto, and drove to NYC. When the FAA closed the US airspace to ALL FLIGHTS, the aircraft that were coming from Europe to the USA, were ordered diverted to 19 Canadian airports. About 37,000 passengers on those flights landed in Canada, instead of the USA. I continued to listen to the radio in my van, all through the day. JimB.
