I moved into my condo two months ago (condo is 2 years old) and found in the last two week my engineered hardwood floor started to separate at one of the joints between the kitchen and dining area. Majority of the separation occurred in one day (about 4mm) and over the course of 2 weeks it increased to 6mm. I have never seen this before and I am completely stumped as to how this could have happened and so quickly in only one location. It almost looks like the entire floor shifted. I doubt the building could have settled this much (I live on the 10th floor). I live in Toronto, Canada where it has gotten pretty dry in the last couple weeks, but again I find it hard to believe that this much separation would be caused by that loss of moisture.
I included a couple photos in this link:

Does anyone have any idea what may have caused this and what I can do to repair it permanently?
Thanks in advance.
