I believe I worded it neutrally.  They did live in a government-subsidized co-op. (NB: They lived there from 1985-1990.  They only paid the additional rent for the last few months they lived there.)
It certainly was controversial at the time, and people protested against them.  With Chow now running for the Mayor of Toronto, it has come up in the campaign, which explains why an event that happened 24 years ago is relevant today.  
Finally, although I cited it, the Toronto Star is certainly not a neutral source (their opinion page, moreso); they have a left/centre-left political agenda, which aligns with Chow's.

If Rob Ford's 1999 arrest is relevant to include in his wikipedia article, why should this not be relevant for Olivia Chow?173.230.182.230
