The plaintiff, Unimac, brought a motion to vary previous orders requiring it to post security for costs in favour of the defendant, Metrolinx.
Unimac argued the orders were based on false and misleading evidence regarding the location of a related action, and that new evidence undermined the credibility of a key affidavit.
The Master dismissed the motion, finding that the location of the related action was not material to the original decision and that Unimac could have discovered the true location with due diligence.
The Master also found that the new evidence would not have had an important influence on the original decision.
