Two Thousand And Sixteen Shareholders Plan [Member]
Disclosure of classes of share capital [line items]
Shareholders rights covenants								The rights issued under the Rights Plan are initially attached to and traded with the common shares, and no separate certificate is issued unless a triggering event occurs. The rights become exercisable only when an acquiring person, including any party related to it, acquires or attempts to acquire 20% or more of the outstanding common shares without complying with the “Permitted Bid” provisions of the Rights Plan or without approval of the Board of Directors. Subject to the terms and conditions set out in the Rights Plan, each right (other than those held by the acquiring person) will permit the holder to purchase for the exercise price that number of common shares determined as follows: a value of twice the exercise price divided by the “Market Price” (defined under the Rights Plan as being the average weighted trading price per common share for the 20 consecutive trading days through and including the trading day immediately preceding the relevant date) on the common share acquisition date (defined as “Stock Acquisition Date” under the Rights Plan). The exercise price under the Rights Plan has been set to three (3) times the Market Price. Under the Rights Plan, a Permitted Bid is a bid made to all holders of common shares and which is open for acceptance for no less than 105 days. If, at the end of 105 days, more than 50% of the outstanding common shares, other than those owned by the offeror and certain related parties, have been tendered, the offeror may take up and pay for the common shares. If more than 50% of the outstanding common shares, other than those owed by the offeror and certain related parties, have been tendered within the above mentioned 105 days period, the offeror must make a public announcement of that fact and the bid must remain open for an additional ten business days from the date of the announcement.
