I was in the Canadian city of Toronto, standing around in the driveway of my house in the Rosedale neighbourhood with two buddies as we all waited on a fourth friend to show up.
The plan for the day was to spend the morning golfing and the afternoon with our wives & girlfriends out on Lake Ontario sailing.
All of us were (and still are) self employed, so skipping out on work was no problem except for that last guy.
While myself and the others own our own businesses, he's a dentist and was held up by an early morning emergency appointment.
That's why he was running late.
Early autumn in Canada is still summer weather, and it was a sunny, warm and gorgeous morning that day.
We had a 9 AM tee-off time booked at a nearby golf club we were all members of and worried we'd be late.
I put the top down on my car and turned on the radio in my car so we'd have some music to listen to and to get the traffic reports.
Instead, we heard news of a plane hit a building in New York and that it was total pandemonium down there.
We all trooped inside and turned on the news just as the second plane hit.
-It's not every day you watch the start of a war on live TV.
My friends didn't realize that's what we were seeing, but I knew it wasn't a coincidence. It was deliberate.
I had it confirmed when a relative in the Canadian military phoned to say we'd just gone on full alert because the Americans were under attack.
(A Canadian General was in command at NORAD that day. So our military realized what was happening even as the US chains of political and military commands froze - and failed - in shock.)
I also knew what it meant for Canada - we invented NATO, wrote parts of its treaty - and I knew war against any NATO nation was war with all of NATO. Meaning Canada was at war too.
It was one hell of a surreal experience none of us will ever forget, along with the Canadian victims of 9/11.
(Citizens of more than 90 nations - including 24 Canadians - died in the 9/11 attacks, not just Americans.)
As a Canadian, my proudest moment was how we handled all the flights bound for the US diverted to our airspace.
Places like the tiny town of Gander Newfoundland took in thousands of panicked travellers, cared for them like they were family, and kept them safe till US airspace was reopened.
Canada took a huge risk Americans have never truly realized or appreciated because we had no idea if there were more terrorists on any of those planes. Terrorists that might settle for crashing planes into Canadian buildings in revenge for their flights being diverted to our airspace.
-We let them land at airports all over the country before closing our own airspace.
Canada could've said, "Screw you" and closed our own skies to those flights and let them all run out of fuel and crash at sea or on US soil but we did the decent, honourable thing and saved thousands of lives.
As it turned out, there weren't more hijackers. But nobody knew that on the morning of September 11th, 2001.
