Here is video from yesterday's tornado in Ottawa, Canada.
I was surprised this morning to read the local news media in Ottawa and find that some were calling yesterday's tornado a downburst. It was a tornado. The map below, from U.S. weather radar, shows the path of the rotation.
Based on the damage photos I have seen, I'm sure it was at least an EF-2 intensity tornado and, perhaps, and EF-3. There is more here.
