There have been several instances where the company has used "closed" to refer to the signing of the deal and receipt of first payment only.  TM seems to have muddied the waters a little bit lately by stating in the 2020 Q1 report when discussing the debentures: "The Company has not notified the trustee or the holders of the debentures that the sale of DenseLight has been completed and will not do so until the final payment of $5,000,000 is received from the Buyers, which is expected on or before May 31, 2020"

So, officially (legally?) closed but definitely not completed.  At this point who cares if/when it "closed", the only thing that matters now is the completed part, and for some, as long as it remains incomplete there is also a chance it could become "unclosed"....
