Today on The Current:

New variants of the coronavirus have arrived in Canada. What does that mean for the trajectory of the pandemic? Matt Galloway talks to Dr. Charles Gardner, medical officer of health for the Simcoe Muskoka District Health Unit; Dr. Catalina Lopez-Correa, executive director of the Canadian COVID Genomics Network; and Dr. Lauren Lapointe-Shaw, a health services researcher and physician with the University Health Network and the University of Toronto.

Plus, Canada expects 40 million doses of the Moderna vaccine in 2021, but at the current delivery rate, those doses would take years to arrive. How does the company plan to ramp up to meet delivery targets? We ask Patricia Gauthier, head of the company's Canadian operations.

And Sen. Murray Sinclair will retire from the Senate on Jan. 31. He talks to Galloway about his groundbreaking career, and warns that unless systemic racism in Canadian institutions is addressed, it will "dominate the conversation for years to come."
