Wiki also lists this number as the current R0 (though without a source, as far as I can see). Found this study too in attempting to answer your question: https://www.fil.ion.ucl.ac.uk/spm/covid-19/forecasting/

And learned the difference with Rt today (which some others are quoting, eg for Alberta), is that Rt is computed, while R0 is a guess based on a model, to try to normalize Rt so that it is more comparable over time and place. So I thought that was cool!
