My take is that Covid-19 is coming to a place near all of us within the next few months. The obvious precautions - social distancing, frequent hand washing - may not prevent contracting it. Then it is a case of how bad is it in your case? The problem is, if you do get it then it is likely in an infection hotspot that popped up. Then you need to self isolate and not travel.
If your symptoms are bad you may need medical care, or even a ventilator. Now Canada probably wont discriminate against aliens (you will be one in their country) but medical facilities in this scenario will be stretched, and triage requirements may see you down the queue, or miss out, on the degree of medical care that's optimal for you.
Some of these things could unfold in your home country as well, but I'd rather be at home than in another country if an indefinite ban on travelling even if not infected is put in place. And if infected, you ain't going nowhere if the medicos are on the ball, and my guess is that is going to be strongly enforced.
In some respects you are better placed than someone visiting the USA. A modest period of medical care in the USA will bankrupt most people. I doubt travel insurance to cover covid-19 is possible anymore, and even if it were there would be total $ limits. I will not be visiting the USA for any reason for the foreseeable future. I probably would not contract the virus there, but might get it on the 14 hour flight to get there. I could not afford medical care in the USA.
Tom Hanks and his wife now have covid-19, and are about an hour down the road from me. As yet it is not clear where they were infected. He will have to sty for a while, in isolation, but no doubt will be well looked after and be able to pay whatever it costs. A lot less than in the USA I'm sure!
I'm not going far from home, but will still use the boat a lot. There are always things on the 'to do' list - so its an opportunity to have boat-time and get ahead (or at least catch-up) on stuff.
