RE: Relation to Starlight US looks like it is:

Starlight Investments Ltd. ("Starlight") is the promoter of the Fund and will also act as manager of the Fund. Starlight is a privately held real estate investment management company that currently manages approximately $3 billion of Canadian commercial and residential properties.
there are a lot of reits that have "sponsorship" from larger entities and acquire property from them - rmm.un/cwt.un, par.un / league financial partners, mrg.un + mrt.un / mrc.
I'm not exactly sure though that any of them acquire assets from their sponsors as frequently as tn.un does from starlight. this could be because tn.un is new and management is trying to ramp them up to a decent size with the expectation of cooling off on the true north acquisitions once they achieve a particular market cap...maybe? Just thinking out loud.
Also wondering if it was always the plan to spin out the US multi family assets as its own entity or if they would have prefered to sell those assets to tn.un but true north's shareprice is hindering capital raising efforts. probably not. maybe they are trying to imitate a mrc / mrt.un / mrg.un or a d.un / di.un / dir.un model.
