Stocks in play: CannTrust Holdings Inc.

Shares slipped Friday after the cannabis company said it is laying off as many as 140 people — roughly one quarter of its workforce — while it works to regain its federal licences to sell and produce pot. The Vaughan, Ont.-based pot producer said late Thursday there will be a series of phased layoffs between late October and the end of the year. The cuts are expected to result in monthly cash savings of about $400,000 and cost up to $800,00. CannTrust Holdings Inc. shares T.TRST are trading down 12 cents at $1.62.
