Looks like a CG Vessel was docked at Halifax Shipyards today, however it was not the Louis St Laurent. The new Corporal Teather appears to be docking, presumably to address an issue identified on trials.

Update, The CCGS Louis St Laurent sailed at 1100. No destination is given

UPDATE 1500 : that was fast. shes out and trialing in the basin. Update 2200: Apparently this drydocking was to correct a Sonar issue
