In 2021 the Capital Markets Tribunal approved a settlement with Trevor Rosborough, a former mutual fund dealing representative who admitted illegal tipping and insider trading in WeedMD shares in November 2017. He agreed to an eight-year trading ban, a C$35,000 penalty and C$5,000 in costs.

A dash means the release did not state a figure we could extract, not that the figure is zero. Penalty and disgorgement are stored separately so aggregates across the library do not double-count the same dollars. This regulator states penalties in CAD. The figure is recorded as published and is not converted, so it does not appear in the USD totals or medians used elsewhere on this site.

What is alleged to have happened

The Ontario Securities Commission filed its statement of allegations on November 9, 2020 against Rosborough, Taylor Carr and Dmitri Graham; Rosborough's settlement agreement is dated July 28, 2021.

Staff alleged illegal insider trading and tipping by an experienced registrant and his associates. In his settlement Rosborough admitted tipping and trading in WeedMD Inc. shares between November 10 and November 21, 2017.

His order imposes an eight-year trading and acquisition ban, a reprimand, a C$35,000 administrative penalty and C$5,000 in costs. The outcome for the other two respondents is not summarised here. The record previously described the matter as dismissed, which is wrong.
