While the last year of the Roadster for the USA was in 2019, it continued for one more year as a 2020 model in Canada & Australia. Here is an archived page showing the 2020 Roadster in Canada:

However, it looks like Nissan couldn't even wait for the 2020 model year to conclude to give the Roadster a full year run for 2020 and production on the Roadster has ended early.
I just checked the website for Nissan Canada and the 2020 Roadster has been removed!

Then I also checked the website for Nissan Australia and it's gone from there too:
