In proportional representation, who do I call when I have a local issue that is in a federal responsibility?
If you propose a mixed system, most are local MP with a few extra spread out amongst the other parties, what ridings do they represent?
There is no perfect system, but within a representative democracy where the regional concerns are diverse, unlike most European countries, Canada is the physical size of Europe, proportional representation will always over represent the needs of dense parts of the country.
