As pandemic restrictions continue to lift across the country, we’re joined by Zain Chagla, an infectious diseases physician at St. Joseph's Healthcare in Hamilton, for a look at where we are with COVID-19 in Canada, and how to weigh the risk factors for yourself. (And we promise — there’s plenty of good news!)

In a flash, a view of Ukrainian civilians fleeing down a street in Irpin becomes only concrete dust. The scene captured in a video Sunday shows a mortar shell falling in the street, killing three family members and a family friend — including two children. This is the kind of danger looming over the people of Ukraine. Some have decided to leave their homes and loved ones behind to risk an escape. Others who must stay are helping to ready a resistance to the overwhelming Russian military power. CBC senior correspondent Susan Ormiston is in the city of Lviv in Western Ukraine, where she’s been talking to Ukrainians, both those who are fleeing and those getting ready to fight. Today, she brings us to a train station, a border crossing, a bomb shelter and a barricade, and explains how Ukrainians have made these impossible choices — if they had any choice at all.

A new battlefield in Ukraine has opened up as each side fights to control the narrative of the ongoing war. Some experts say Ukraine and its allies are winning the information war by implementing a multifaceted strategy that includes pushing David and Goliath stories – even ones that may not be true – and creating a phone line where Russian parents can check in on their conscripted sons. On the other side, Russia – a country known for its relative success in shaping international media narratives – is clamping down. Today on Front Burner, Peter W. Singer, a senior fellow with the New America think tank, takes us to the front lines of the information war and explains why this fight matters.

More than a million people have fled Ukraine into countries to the west, as Russian attacks continue. The refugee crisis has spurred an outpouring of international support, as neighbouring European countries open their borders and homes. But the support this time is strikingly different from how some countries have responded to refugees from other conflicts — like Syria and Iraq — who were kept out, in some cases with violence. The distinction is especially stark, after stories have emerged of some Black and Asian refugees fleeing Ukraine facing violence, harassment and racism at the border. This week on Nothing is Foreign, CBC’s new, weekly world news podcast, we hear from people on the ground including those who have experienced discrimination and explore how governments can treat skin colour as a visa. Featuring: Tatiana, Alexandra, Nastia, Rubi, Ahmed, all refugees from Ukraine. Sara Cincurova, a journalist covering humanitarian issues at Ukraine-Slovakia border. Chris Melzer, the senior spokesperson of the United Nations High Commission for Refugees (UNHCR) Poland.

You can’t understand the chaos in Ukraine without understanding Vladimir Putin. The Russian president rose to power as a wartime leader, and that legacy has shaped his approach through decades. Ben Judah is the author of Fragile Empire: How Russia Fell In and Out of Love with Vladimir Putin, and senior fellow at the Atlantic Council’s Europe Center. He spoke to us about how Putin sees the world and what his past could tell us about Ukraine’s future.

Before launching his latest military attack on Ukraine last week, Russian President Vladimir Putin waged a counterfactual war on a century of the country’s history. In a nearly hour-long address, Putin claimed that modern Ukraine was an invention of founding Soviet leader Vladimir Lenin, and that Soviet Moscow gave Ukraine its independence in a historic mistake. Ukraine overwhelmingly voted for its own independence in a referendum in 1991. While Ukraine’s modern history has since been marked by corruption, Russian influence and episodes of violence, its people have also staged protests and even revolutions to protect their independence. Today on Front Burner, what two decades of Ukraine’s struggles with Russia tell us about why Ukrainians are still fighting today. Former NPR Moscow correspondent and current Wilson Center fellow Lucian Kim brings us the key events, many of which he reported on from Russia and Ukraine.

Since Russia invaded Ukraine last Thursday, Western powers have remained steadfast on one point: They will not engage Russia in a hot war to defend Ukraine. Instead, they are piling on an increasingly punishing slate of economic penalties. Today, we’re going to break down some of the key sanctions, and look at their current and potential impacts. First, Giles Gibson, a correspondent for Feature Story News, will give us a view from Moscow, where people are already starting to feel the effects of the penalties. Then, we’ll speak to Ian Talley from the Wall Street Journal about what exactly these sanctions are — and whether they’ll work to limit Russian President Vladimir Putin’s actions.

On Feb. 19, Jean-Luc Brunel, a top French model scout and longtime associate of the late convicted sex offender Jeffrey Epstein, was found dead in his Paris prison cell. The 75-year-old was being held on suspicion of sexually abusing minors and sex-trafficking. Allegations against Brunel date back to his time as the head of top-ranked modelling agency Karin Models in the '80s and '90s, when he had close personal relationships with Epstein and other powerful figures. The long-running investigation into Epstein revealed ties to Brunel and the role he may have played in a global sex-trafficking ring that potentially targeted thousands of underage women. Today on Front Burner, we hear from former models Heather Braden and Thysia Huisman, who say they were among Brunel’s victims while they were underage and living in New York and Paris in the ‘80s. Then, we talk to The Guardian’s Jon Henley about the circumstances surrounding Brunel’s death, which echo that of Epstein’s, who died by suicide in prison. Brunel's death has ignited a firestorm of questions, even conspiracy theories, as another purported sex trafficker dies before anybody gets answers.

On Saturday morning, as war shook his country, Ukrainian President Volodymyr Zelensky posted a defiant video to his Facebook page. Standing outside, on the streets of the capital, Kyiv, he said: “There has been a lot of fake information online that I am calling on our army to lay down their arms and to evacuate. Listen, I am here. We are not going to lay down anything. We will protect our country. Our weapon is truth. And the truth is, that it is our land. Our country. Our children. And we will protect it.” Today on Front Burner, with BBC World Service’s Kateryna Khinkulova, we trace Zelensky’s path from playing the president on TV to leading the country through a Russian invasion.

From David Ridgen, the creator of Someone Knows Something, comes the new investigative podcast The Next Call. Tackling unsolved cases through strategic phone calls. In the case of Nadia Atwi, on December 8, 2017, Salwa Atwi arrived at her daughter Nadia’s home in Edmonton as part of their regular carpooling. But Nadia didn’t come outside, and the 32-year-old kindergarten teacher was never seen again. Edmonton’s Muslim and Lebanese communities pulled together to search in the days following. Initial searches seem promising, as Nadia’s car is found in a park with her phone inside, but four years later there is still no sign of her. More episodes are available at: smarturl.it/thenextcall
