A "JV" is a Joint Venture. It is a similar to a business partnership, but it purely economic, where in a partnership there is a shared legal liability and other connections.
A joint venture should ordinarily be made with a written contract. In civil law there is really no reason I can think of where a joint venture would be found with no contract; possibly someone providing unpaid work on the promise of shares, although this would be more of a constructive trust.
As noted above, a joint venture in a common law relationship is plausible, but onus is on the claimant to prove this.
In Ontario, liens on real estate are normally limited to construction contractors - in the way that you are implying; a mortgage is a type of lien, so there are lots of liens lieing around.
The OP cannot get a lien the way a contractor could. Further, there has to be a proven liability, it is not enough to just make a claim. If the OP gets a court decision that shows money is owed, then he get a restriction on the sale of the property as part of the final order; this is similar to a lien.
