Flycatcher? September 2016 Mississauga

[BetCrooks]

I'm still working my way through last year's migration photos.
Is this maybe an Alder/Willow flycatcher? Or something else again? I don't have a good photo of the bill in profile unfortunately.
It was at the Riverwood Conservancy in Mississauga on Sept 20.

My feeling is Least, which is the most likely species on that late date, but it's probably not possible to tell for sure from this photo.

At 'least' I know it's likely a flycatcher. Thanks!
