Correct, it doesn’t. But it does link to this story:

Images of Halton District School Board teacher in Oakville wearing prosthetic...
Photos of a transgender high school tech teacher wearing large prosthetic breasts in the classroom went viral.
That is quoting The Oakville Beaver, which I assume is a local Oakville paper? It states the following:
What was originally thought to be a hoax, after the Oakville Trafalgar High School teacher came to school in shorts with a tight-fitting shirt over the prosthetic, has since been confirmed by the board.
I’m wondering what that “confirmation” was, though. Were they talking about the announcement the board made, where they said they couldn’t confirm the identity of the person in the photos? Or did they talk to someone on the board directly? Nobody is quoted here.

Please pay more attention. You are presumably referring to the Toronto Sun. The Toronto Star is a broadsheet, not a tabloid, and is openly liberal.
Yes, sorry. If you have two papers with identical names, there’s a chance I might get them confused. It’s like the People’s Front of Judea, and the Judean People’s Front.
I still see major questions. What I’m reading is that Kaylee Lemieux is/was known as Kerry Luc Lemieux. There is speculation that Kaylee is not a trans woman, but Kerry is dressing this way to protest the acceptance of trans rights.
From what I can tell, we don’t know the answers here, and neither does the media (local or otherwise) because the board will not reveal the information. See this article:

Oakville teacher's controversial attire prompts Halton District School Board...
The controversial classroom attire of a transgender teacher, which has created a local and global media storm and flooded the inboxes of Halton District School Board staff and trustees, has
They are not giving out information, citing privacy rights.
“While I understand the desire for information by the public, we will not and cannot publicly discuss any matter that identifies our staff directly or indirectly. I trust the public will understand the parameters that guide us,” said Ennis.
While the above article does refer to Kaylee as a “transgender teacher”… Are we sure? The only reason I’m asking is because the whole discussion hinges on that.
I think that it’s safe to say that the photos are legitimate and identify a teacher at the school. So it seems that we either have a trans teacher dressing in a manner that I (personally) would consider inappropriate (and it doesn’t matter if we are talking about someone trans, cis, nonbinary, whatever). Or we have a teacher being pointedly disruptive. That’s my opinion at least.
(Thank you @RickJay for pointing me toward some of these news sources, this is something I was trying and failing to find earlier. I really do appreciate it!)
