Canada contributes to North American air defence and it's F-18s (to become F-35s) fly norad missions. Americans also contribute, and obviosuly have more fighters. The article says both countries dispatched planes, the americans ended up shooting it down. It was over the Yukon which is very close to Alaska so not surprising both were present. It would have been a bit odd if it was over saskatoon or something

The article answers the question pretty early on: both air forces scrambled fighters.

NORAD is NORAD. They collaborate very closely and it becomes kind of moot who specifically does what.

Second paragraph:

> Both Canadian and US aircraft were scrambled to track down the object which Trudeau says was taken out by a US F-22.

So clearly not.

Their F-18s can't fly as high (without doing zoom climbs) as the F-22 (which has very large control surfaces which help with this).

It was shot down in the Yukon, jets from Alaska were likely the closest to the target.

In the article it said both forces scrambled to down it, but it seems like the americans just got luckier.

Compare with UK and Ireland, where Ireland indeed has a non existant air force and UK a right to defend.

According to the article, they were also dispatched.

I guess the US air forces received order to shoot earlier?
