A few weeks ago an electrical generator appeared on The Esplanade at the rear of the L-Tower. I finally investigated it and see it is there because Toronto Buildings have declared the building 'unsafe' due to lack of life-support system. (They have put an explanation on the fencing.) I assume their own emergency generator is out of order. Damaged when they had their roof-crane accident or ?? Must say that L-Tower (in addition to the unfortunate changes in the design) has had its share of set-backs.
