HouseSigma — "first in Canada to make sold prices publicly available"; inflection point came shortly after the 2018 SCC-final outcome opening sold data on VOWs

Claim. Founder Joseph Zeng describes HouseSigma as "the first in Canada to make sold prices publicly available." HouseSigma hit its "major inflection point shortly after… a federal overruling of board-level sold-data restrictions" — i.e., the 2018 TREB Supreme Court outcome — "sparked a viral wave of site traffic in Toronto."

Quote.

"Sparked a viral wave of site traffic in Toronto."

Source. HouseSigma self-reports / interviews; consistent with the Aug 23 2018 SCC denial of TREB's leave in case 35799/37932 timeline. Accessed 2026-06-21.

Confidence. Single-source for the founder framing; cross-corroborated by the SCC timeline.

Caveats. "First in Canada" is the founder's claim; verify before citing as fact. The causal link from the SCC outcome to HouseSigma's inflection is directionally consistent with industry-wide observations of post-2018 sold-portal launches.

Implication / use. Concrete instantiation of how the licensing fence opening (the 2018 outcome) reshaped the consumer side. Bridges Section 2 (underused layer) to Section 3 (licensing).
