Sorry to hear this. It's not going to be a fun experience either way. Water under your floors is definitely a problem that will continue to get worse.

Gravity pulls water down, so my guess is one of the pipes feeding into your unit is leaking and the water is seeping below your floors and will continue to spread if the leak isn't fixed. I had a similar situation, it was a pipe below my sink that was dripped overnight, into the cabinets and eventually down into the floors. Other possble sources are the dishwasher or your ice maker.

First thing to do is get a copy of your bylaws and find out if there is a chargeback bylaw or anything that talks about responsibility for damages from a strata lot. That will determine how much liability is yours.

Generally speaking, here are your options:

Call the property manager and demand strata sends a restoration company to investigate. The council has a duty to act in this situation because the assumption is the leak is impacting the structure of the building. The crew will arrive, rip out your floors, find the source of the leak and start drying the place out. If they determine the source is from one of your pipes or appliances, you'll eventually be sent the bill (if your bylaws allow that) and you can choose to pay it or claim it against your home insurance.

Or you can call your home insurance now. They'll basically do the same process as above. OR they might tell you to call the strata council first and start with them. If the leak impacts many units and the total damages exceed the strata insurance deductible, the entire claim goes to the strata insurance (unlikely though based on your description).

Or you just call the restoration company yourself and try and keep the strata/insurance companies out of it.

Of the three options, the easiest arguably is start with the strata and let the chips fall where they do. But read your bylaws first!

Either way, your floors will have to be removed, and possibly some baseboards and drywall to isolate the source so expect a lot of repair work that will take a few months.

Last tip, shut the water off at your main shutoff and that is likely to stop the leak. Calling a restoration company today (Sunday) will cost a lot more than tomorrow (Monday) because of weekend/OT rates. So consider waiting 24 hours if you shut the water off.
