Why haven't lilac bushes lost their leaves?

It's winter but these ornamental shrubs still have green leaves
Lilac bushes here in the Thunder Bay area of Northwestern Ontario never lost their leaves before winter set in this year. It's the first time I have seen this and I can only speculate that the hot days we received in late September somehow tricked the bushes into thinking there was still a lot of summer left.
Does anybody out there know the reason? If so, leave your comments.
Lilacs, of course, are not a native species. They originally came from Asia but they are the most widely planted shrub in Canada, according to my tree books.
They are exceedingly hardy and can endure extreme temperatures.
I wonder if the fact they kept their leaves will impact the blossoms next spring?

Hi Dan: Yes we have the same situation in Ohio. We have two pin-Oaks that are still green with no signs of dropping yet.the weather has finally started to get back to normal, but still having days over 50.
I would think you are really enjoying your new sun room now.

Hi Ray,
I am enjoying the sunroom, even though we are still working on the inside doing finishing. It is a great feeling to sit in the room, heated only by the sun, and have it be 25 C inside while outside it is cold and snowy!

Don't worry about the timing of your Lilacs dropping leaves.
I have forsythia doing the same thing.
I would worry more about that gutter downspout next to your bush.
Lilacs don't like wet feet. Well drained slightly alkaline soil is best. Can't imagine what the soil is like when your foundation was backfilled years ago. This bush looks awfully close to your house. I could never figure out why people plant bushes so close to their homes. Don't fertilize late in the fall. They like sun. Couldn't tell what side of house this was. Some mulch around the bush will be appreciated, not your grass. Best way to trim is not just keep cutting down the top. Bushes like some air and sunshine between branches. Cut out any branches that criss-cross themselves and any dead branches. Don't be afraid to take out a few large branches and let the smaller young one grow and thrive. If you have any suckers popping up dig them up and transplant them. You will have a thriving bush in 3 to 4 years.
Regarding the bush in your picture, I would be transplanting it out in your yard with nothing on all four sides of it this spring.

Update: Our lilacs' leaves turned brown in mid-December and fell off during a violent wind storm.

Red Lake ice-out moves to May 1

 There's bluebird weather in the forecast the next two weeks and that makes me move my final ice-out prediction to May 1 or one week ear...
