I'm in the age group that was one of the first cohorts who only learned Metric in school in the 1970s.
While we do use Imperial for stuff here, I would still say the conversion was successful in that everyone in my cohort and later knows/remembers/understands the metric unit alternatives to the Imperial units that we still use.
Obviously we still use a lot of Imperial units due to our proximity to the US, but if the US were to completely convert to metric, there wouldn't need to be much (if any) re-education for Canadians younger than 50.
Anyway, my point is I don't think its fair to call a nation converted when it still has both officially-recognized non-metric units and official uses for them (such as in aviation). I also disagree that these are driven entirely by the US, as Canada still uses a few non-metric units, like the Avery bushel, that the US does not.
