Conservative Leader Erin O’Toole is accusing China of condemning Canadian Robert Schellenberg to death in retaliation for Ottawa’s arrest of a Huawei executive. His comments come as Canadian businessman Michael Spavor awaits his own verdict in China hours from now in a case that Canada has criticized as “hostage diplomacy” and also appears to be a tit-for-tat move by Beijing. Mr. O’Toole, speaking to reporters in Oakville, Ont., Tuesday morning, was responding to a Chinese court’s decision Tuesday to reject an appeal by Mr. Schellenberg of a death sentence for drug trafficking.
