I don't work downtown, really, but I'm both close to downtown and near the Queensway, and the first sign we had was one of my coworkers saying "there have been a lot of sirens today".
It turned out that was just the tip of the iceberg.
Much of downtown was under lockdown most of the day. We had updates from federal politicians ad provincial politicians and municipal politicians. The three police forces were all involved.
And now, almost twelve hours later, there's still a lot we don't know.
Two people died. Three were injured. Thousands were scared or worried. Hundreds were busy performing first aid or investigating or helping in some other way.
And, in the end, most of us made it home. Prayers for those who didn't.
