And one can fix this disparity by increasing the number pf MPs in the other provinces to a ratio to population that is close to the average ratio of the over-represented provinces and cut their pay to $40-50,000 / year. You get rid of a lot of the professional politicians and add so many MPs that the PM cannot whip them with the hope of a cabinet or committee position. The power of the PM to control policy and the legislative agenda is diminished, the MPS, having little hope for the power of a seat on cabinet or committee works harder on the issues of their individual ridings.
Smart people that truly want to serve their country will still come forward, as will idiots. But with the trough far less lucrative and the chances of actually moulding legislation and policy to suit an individual's ideology being quite slim, the parties themselves will become more diverse with the return of red Tories as well as blue Liberals and green Tories and Liberals. Leaders will need to compromise to get the support of their diverse members to gain and hold the leadership.
If you really want to shake things up, do a constitutional amendment that sets MP's salaries to be a percentage of gross national product less national debt. See if that can control their proclivity to spend money we don't have.
Adding more MPs is pointless. Remember, you pay not only for the MPs salary, but also the overhead associated with their position as well as the salaries of staff to support them.
Some provinces are over represented, and others under represented. The only province that has representation equal to its share of the population is Quebec, which I think is by design.
The representation ratios are provide below. Numbers above one are over represented (and by how much), those below one are under represented.
AB 0.859
BC 0.951
MB 1.148
NB 1.407
NL 1.408
NT 2.405
NS 1.237
NU 2.874
ON 0.931
PE 2.898
QC 1.001
SK 1.310
YK 2.859
The territories have high numbers because they only have one seat. The high numbers for the smaller provinces is due to the number of senate seats they have, as well as the fact that their populations are more or less flat whereas the populations of BC, AB, QC and ON are growing. The ratios change every year as population numbers change.
In order to make the seat distribution representative, the following adjustments would have to be made (rounding up or down to an integer):
AB +6 seats
BC +2 seats
MB -2 seats
NB -3 seats
NL -2 seats
NT no change
NS -2 seats
NU no change
ON +9 seats
PE -3 seats
QC no change
SK -3 seats
YK no change
In addition, rural ridings tend to have fewer voters than urban ridings, in part because it is designed that way, and in part because of population growth rate differences. In other words a fairer distribution would also change things within provinces, with cities getting more of a provinces seats and rural areas fewer.
