Yes, Jubellee, property records complete with liens/charges against the property are public information. They can be obtained by anyone who wants to obtain them and can be very informative in complex cases like this.
"All registered and deposited records are available to the public (for a fee) to search title or obtain information about the ownership of real property."

IMO, you're correct in saying that it's possible and I'm sure it has happened. The DM case is a bit different. MSM and releases from LE have provided the valuable connectors. The Waterloo Hangar and Hangar 4 in Toronto: this is not public info via land titles and no one would know that DM was involved with any Hangar from land records. Until DM's arrest, there was just minor MSM coverage on WM's venture. MB's house? There was no reference to MB prior to the trailer being found. It would have been extremely difficult to locate MB or associate her with DM by land records since she was never on title with any of DM's properties, and even then it would have been MM. IMO, that's why the trailer went to MB's house and not one of the other properties that had a DM association JMHO
It is easy to find someones family especially with access to people who know DM or access to registries. When you apply for most government documents in Canada at least, you are asked for your mothers maiden name. Most government agencies would have access to this information. Anyone can ask questions also of people that know DM. If you google DM up comes Wayne and Carl Millard...and with Wayne along comes MB....for example their wildlife adventures etc were already online as was the obit for CM which gave the name Madeleine. If you know where to look you can find quite a lot. MOO
The incinerator-apparently its difficult to identify cremated remains, but not impossible because of bone/teeth fragments left behind. This article mentions that if they have an idea who the remains belong to and know their dentist, identification can be much easier. Juballee, I remember it being discussed in another thread that the opening of the SN250 was not big enough for an average man's body, even though it had the capacity for the volume. IMO, unless DM was going to start farming chickens or something, he may not have had the right equipment to do the job. JMHO, but I don't think we've heard the end of the incinerator yet...MOO :scared:
I;m sure people will continue to sleuth about the incinerator..... and until more info comes along its up for speculation. IMO a body would have had to have been sawed into pieces to fit into that incinerator and I don't believe that occurred JMO.... LE did not say TB had been found in parts. JMO
"But it's rare, even in the most severe burning, that "some fragments of dental evidence" wouldn't exist."
But he was identified extremely quickly so that suggests to me that he was at least somewhat identifiable JMO
