Nobody really knows, I'm hoping to travel to Japan at the very end of this year or sometime next year. I'm from the UK. There is no way of telling though unfortunately.
However, there is a good way to measure around when you might be able to travel.
Take a look at how Japan are slowly easing travel restrictions with certain countrys - Australia, Vietnam, Thailand, New Zealand - because they have handled the Coronavirus situation relatively better than other countries. Therefore, they will let these countries travel to Japan first.
They won't let people from those countries travel on tourism though, at least not yet. First comes business travel, then students and finally tourists. On top of that, it'll only be 250 people from each country per day that can enter and they must submit a document that proves they were tested for the Cornavirus before they came to Japan. Then, once in Japan they must submit an itinerary that details their visit followed by another Cornavirus test.
So the best way to figure out around when you may be able to travel to Japan again is to look at the situation with your own country. I'm not very sure how Canada have been handling the Coronavirus, but if your country is handling it well then you may possibly be able to travel at the end of this year.
My advice would be to keep an eye on Kyodo News (They update a lot about the Coronavirus in relation to Japan) and to also keep a close eye on how Canada is handling the Coronavirus.
I'm from the UK and we've been handling the situation very poorly with a high death-rate and a lot of infections. It's starting to get better, so I'm being optimistic about going to Japan in November/December. Though, I'm yet to book any flight tickets because I think deep-down the UK won't be going to Japan until perhaps February or March in 2021.
Finally, I'm not 100% sure about this, but I think that Canada, the UK, America, China, Germany and perhaps other countries with a high tourism rate in Japan could be very slightly fast-tracked into a return to Japan considering they contribute significant amounts of GDP. But right now I think Japan wants to focus purely on keeping it's country safe.
Bottom line, keep an eye on your country's status with the Coronavirus and do check frequently with Japan's Coronavirus latest. The better your country is doing - the closer you are to a flight to Japan.
I'll leave a link to Kyodo for you, it's definitely a great source.
