Guest: Kieran Leavitt, politics reporter for the Star The fourth wave in western Canada has become a crisis. COVID-19 patients in Alberta are dying at four times the rate of the national average as the province leads Canada in active cases and deaths. After a sharp uptake when vaccines were first available, Saskatchewan's vaccination rate has stalled and now ranks as the lowest of all provinces.  We look at the political decisions in Alberta and Saskatchewan that brought them to this moment and whether they can control the fourth wave.
