For a concrete example of what @asterfield@lemmy.world said, if there are 10 workers, and 9 of them are making minimum wage ($17.40 in BC), then the remaining worker would make $192.90/hr. $1772.40/hr if 99/100 make minimum wage.
Median is definitely the better measure, though no single measure is adequate to answer the question of whether Canadians are better off than they were last year.
