This is Cryoseim
"Around 11 p.m. Xmas Eve, people reported hearing a loud “boom” in
Toronto, Newmarket, Aurora, Belleville, Richmond Hill, and Sutton. Not
only was the boom heard, but it rattled houses, leaving many to believe
that a tree had fallen on their rooftop...
The most likely explanation is that it was a cryoseism, also known as a frost quake.
Cyroseisms
are rare, localized seismic events that occur when a sudden drop in
temperature freezes the groundwater, which then expands and cracks the
soil and rock. The crack will release a sudden burst of explosive
energy, resulting in a loud noise and the shaking of the ground. They
usually occur between midnight and dawn."
