I assume you are an American as you do not seem to understand how a parliamentary democracy works or how the Canadian system of governance works. Mr. Trudeau can be removed from office at any time by a non-confidence vote, and if he was as incompetent as Mr. Trump he would already have been removed. In Canada we have a four party system (five if you count the Greens). We also have a much higher percentage of people voting. So if you calculate the popular vote based on the number of eligible voters rather than the number of voters you get a different number. Also, only people in his own riding voted for Trudeau directly so the comparison is in fact meaningless. Different systems, different outcomes.
