Speaking of Canada... and balloons...
Didn't you guys have some weather balloon that went awry back in the day and it was headed for Russia?
As I recall, your Air Force tried, but couldn't shoot it down. And they did try. Pretty hard if I remember correctly. Guess that's why Justin gave this one a pass as it crossed over Canada.
EDIT:
Found it.

Rogue balloon - now over Russia
US maritime dispatched a plane surveillance plane from Iceland to look for the balloon using radar, but failed to locate it.
"The radar they were using was for surface searching and they weren't able to detect the balloon in the air," said US Air Force Lieutenant Carla McCarthy.
The British and Canadian airforces were equally unsuccessful.
25 storeys high and as wide as several football pitches
Two Canadian air force CF-18 fighters fired more than 1,000 rounds of cannon shells into it off the coast of Newfoundland.
An Icelandic official said the Canadian attack caused extensive punctures but failed to release the helium gas from the balloon.
But Lieutenant Colonel Steve Wills of the Canadian Air Force said
he was not embarrassed by their failure.
"With something like this, which is stationary in the air when the CF-18s are flying very, very fast, it is difficult to shoot it," he said.
