My dad, stepmom and brothers live in suburban Detroit, not that far from Toronto. My dad has a thing for Windsor, and a park somewhere on the lake called Rondeau (I think that's how it's spelled) I do know the climate in the region. I was trying to mix in a climate joke that evidently fell flat. My bad, I guess I still think it's possible that some shallow freezing along faults, either known or unknown, could be plausible.
I read yesterday on aol news that the there were a lot of people in the midwest that heard a large boom sound.
I think I like my personal theory best. It's damn cold up there in the frozen north. Damn cold. Therefore, so is the ground. Water seeps in in warmer temps, freezes in voids & faults (you do have fault lines up there) The plates are constantly moving to some degree or another, right? Then by logical deduction, pressure is also always on the faults no matter where they are, wanting to be released.
The more direct version: I think the northern faults are having a tougher time moving & such with frozen water in their vicinity or directly on/in them, and the pressure stress is higher, and fracturing the frozen bonds while they move & shift around. Hence, BOOM.

Wonder if it had anything to do with this?

then Phone a local Science / Geology Museum and ask if they can perhaps explain the cause - or likely - cause of such Sounds. Chances are they will put you through to someone more local who can explain just how such sounds are made (Hopefully).
A rare phenomenon, cryoseisms usually "occur when temperatures go from above to below freezing," says CBC News meteorologist Michelle Leslie.
"Water in the surrounding soil and rocks freezes. As water freezes, it expands, putting pressure on the dirt and rocks," she says.
"When the pressure build-up is too much, the dirt or rocks will crack, and you hear a loud boom."
They tend to occur between midnight and dawn, the coldest time of night and are very localized, so residents a few blocks away may not have heard the Christmas Eve or Christmas day booms.
‘Frost quakes’ blamed for waking GTA residents with a boom
In the Greater Toronto Area, very cold weather may have triggered “frost quakes” early Friday morning that woke residents with a boom.
Many people in and around Greater Toronto reported explosions throughout the night, with some seconds or minutes apart. No damage or injuries were reported.
A “frost quake,” scientifically known as a cryoseism, is a rare weather phenomenon set off by a sudden drop in temperature, from above freezing to below 0C, causing water in the ground to freeze. Soil or rock saturated with water will expand, putting pressure on surrounding soil and rock until an explosion is caused.
“They are incredibly rare,” Environment Canada meteorologist Geoff Coulson said. This week was his first experience of them in 30 years, he said..
really?....no discussion or speculation if it could be sonic booms from freakishly high speed aircraft?? seems to me that if the sound was that loud and so widespread, cracking ice would leave a massive crevasse in the ground
