I can understand why the IOC (and perhaps Japan) are delaying the decision. But the Canadians are probably right, and their lead will be followed.<p>Can't see many countries risking their top athletes right now, anyway.<p>Even the opening ceremony would be a massive risk according to what's currently known.<p>A lot can happen in 4 weeks, but the changes that need to take place in time for the Olympics (Vaccine? Effective treatment? Scalable testing and containment?) appear to be a long way off.<p>And what happens if the IOC end up needing to ban certain countries still fighting the issue?
