Authorize US jets you mean? Canada is a close US ally, norad allows both US and Canada to learn about the object at the same time, and US may have offered to shoot it down with Canada’s permission since we probably have some new patrols in the area since Friday’s ballon

The US was monitoring it on Friday:
> A statement from Pentagon spokesman Brig. Gen. Patrick Ryder said the object shot down on Saturday was first noticed over Alaska on Friday evening. Two F-22 fighter jets “monitored the object” with the help of the Alaska Air National Guard, Ryder’s statement said, “tracking it closely and taking time to characterize the nature of the object.”
> Defence Minister Anita Anand said in a news conference the "small, cylindrical object" was about 40,000 feet above ground and downed — due to possible risks to civilian aviation — at around 3:40 p.m. ET about 100 miles from the U.S. border in central Yukon.
> A senior government source with direct knowledge of the situation told CBC News that the Canadian government was first alerted to the object Friday night when it was still travelling through Alaska.
> The source added the object crossed into Yukon on Saturday morning and Trudeau ordered the shoot down by whichever country arrived at it first.
So it looks like the US 'took too long' to decide to shoot it down, and once it crossed the border Canada had final authorization. The US jets just happened to be closer (CA jets were scrambled as well).
A close enough ally that the US was willing to sell nuclear tipped SAMs to Canada during the cold war. The only reason it didn't happen is because the general public flipped shit when they found out about the plan.
