York Regional Police say the coroner has been called to an apartment building in Thornill, where it appears a man drowned in the swimming pool on Thursday morning.
The elderly man was found floating in the pool near Yonge and Clarke just before noon.
CPR was performed, but the man couldn't be revived.
Police say the death does not look suspicious, but they don't yet have a cause of death.
They haven't released his age, only to say he's elderly.
