That is weird tbh.. there website mentions walk ins are openAre you sure? I went for a walk-in in March at BLS Toronto (Lawrence location); and when I got there, they had already told the people gathered that they don't accept Walk-Ins anymore and to go home. I waited there in -10 C for 2 hours, and the walk-in line never moved at all.
even CGI Toronto website has this update end of Jan: https://www.cgitoronto.gov.in/alert_detail/?alertid=225
