The prime minister was mobbed by members of the Liberal party attending “community visit” by Mr. Trudeau and Liberal candidate Jean Yip at Bridlewood Mal. There is a Dec. 11 byelection in Scarborough-Agincourt to fill the seat left vacant after MP Arnold Chan died in September. When Trudeau arrived at Bridlewood mall around 5 p.m., hundreds of people started reaching for the prime minister’s hand as he was led into a crowd of people to head for the food court. Less than two minutes later, his security detail started guiding the prime minister back towards the mall’s entrance as he continued shaking hands with those around him. The occurrence has led to talk Thursday about safety planning.
