After the morning terror attack by an Islamist terrorist on Parliament Hill in Ottawa, much of Canada's capital remained in lock down for much of the day. Thus it was no surprise that the NHL postponed the Ottawa Senators- Toronto Maple Leafs game at the Canada Tyre Centre scheduled for the evening.
Social media allowed NHL players, coaches and reporters to express messages of sympathy and solidarity with the besieged Canadians.
For me, the most touching tribute to our neighbors to the North was at Pittsburgh Penguins-Flyers game in Pittsburgh where the crowd sang O Canada, the Canadian National Anthem.
Neither club was from Canada or a border town, yet American hockey fans recognized this was Canada's 9/11 moment and showed solidarity.
