Monday is bylection day across Canada as four constituencies will elect new MPs. In Scarborough-Agincourt, Jean Yip (Liberal) will face off against Dasong Zou (Conservative). Ms Yip is a political and sentimental favorite as the widow of the late MP Arnold Chan, who died prematurely of cancer. Mr. Zou is an IT manager for the Royal Bank. There are also elections in Bonavista–Burin–Trinity in Newfoundland, last held by Liberal Judy Foote, Battlefords–Lloydminster in Saskatchewan, last held by Conservative Gerry Ritz and South Surrey–White Rock in B.C. last held by Conservative Dianne Watts. The Liberals are expected to hold onto the Ontario and Newfoundland and Labrador seats, while the Conservative seat in rural Saskatchewan is also a stronghold for the incumbent party. But the B.C. riding of South Surrey–White Rock will be hotly contested between the two parties — putting Scheer at risk of suffering a second byelection loss as leader.
