Tesla has deployed a new software update tonight, 2021.36.5.5, which so far appears to be going to Model Y vehicles, including some in Canada.
The update was first noted by Drive Tesla reader Thomaz, who reported receiving it earlier this evening.
UPDATE: This update is also rolling out to Model 3 owners.
The update contains the same features found in the main 2021.36 branch, plus another one that talks about the new capabilities of the mobile app.
