In total deaths Canada is definitely doing better with only 41.5% of the USA death rate per population.
Statistics can be misleading:
Quebec Canada death rate per million is .0678%
Maine USA the death rate per million is .0102%
They share a border and Quebec’s death rate is over 600% higher…
& Quebec’s .0678% death rate is higher than the USA’s .06
At 1,600 deaths per 1,000,000 people, Montreal is among the worst hit urban areas in North America. At the end of May, the city's death rate was also higher than most American cities, including Chicago and Los Angeles. Quebec’s death rates are worse than those in Italy, Spain and the United Kingdom

In the continental USA:
23 states are democrat run, have 117,735 deaths, 59.54% of all deaths
26 states are republican run, have 79,996 deaths, 40.45% of all deaths
Liberal states (3 fewer) have 60% of the deaths…..
There can be a lot of variables when comparing two countries, or even regions within one country:
--What type of exposure from international travel did each receive
--what percentage of the population is in rural areas
--what percentage of the population is in 1mil + pop cities
--what is the overall health and resulting comorbidity
--what percentage of the population is over 60 years old
--and with covid how well were seniors in nursing homes protected
--what preventative/treatment measures that were/weren’t taken
--when did a region or country get its first covid case, ie. was it one of the first to get the spreading covid or latter
You state that Canada and two islands (Australia & New Zealand) handled it better than the USA – I would really appreciate you letting me know what they did differently that accounts for their lower rates
