When a company goes public, insiders and early investors usually agree not to sell their shares for a lock-up period, most often 180 days. When it ends, a large number of shares can become available for sale, and the stock often comes under pressure before and after the date. This list shows stocks on the Toronto Stock Exchange that are 170 to 190 days past their IPO, with the days left to the 180-day mark. Actual lock-up terms vary; check the prospectus for exact dates.
