Yes by a strict population-share benchmark, in both the House and especially the Senate. But the two chambers use different constitutional rules, and neither guarantees exact representation by population.
Under the 2023 representation order, Alberta has 37 of 343 House seats, about 10.8%, compared with roughly 11.5% of Canada's 2021 census population. In the Senate, Alberta has 6 of 105 seats, about 5.7%. Both figures are below Alberta's population share. The House starts from population but includes constitutional protections for smaller provinces; the Senate was deliberately designed around regional and provincial representation rather than population. Alberta is therefore underrepresented by a strict population benchmark without being denied seats under the current legal formulas.
Yes, if the benchmark is strict representation by population. Alberta has about 10.8% of House seats versus roughly 11.5% of Canada's 2021 population, and only about 5.7% of Senate seats. But the two chambers are designed differently: the House uses a population-based formula modified by constitutional protections for smaller provinces, while the Senate is explicitly structured around regional representation rather than population.
Alberta has more residents per MP than the national average under the latest House redistribution, and its Senate representation is much further below its population share. In the House, Alberta has 37 of 343 seats; in the Senate, it has six of 105. On a one-person-one-seat benchmark, the province is underrepresented in both chambers, particularly the Senate.
Underrepresentation by population is not the same as being denied seats that Alberta is legally entitled to. The House formula includes the senatorial clause, grandfather clause and representation rule, which protect some smaller provinces and therefore prevent exact proportionality. The Senate follows a different constitutional design entirely: seats are assigned by provinces and historic regional groupings, not redistributed according to population growth. Changing the Senate disparity would require constitutional reform, not an ordinary electoral-boundary adjustment.
The representation grievance is factually real under a population benchmark, but combining the House and Senate shows why the remedy is not one simple seat count: the two chambers embody different constitutional compromises.
The answer depends on the benchmark. Alberta is underrepresented relative to strict population proportionality, but both chambers are operating according to the constitutional formulas that govern them. Future House redistributions and population shifts can change the House gap; the Senate gap is far more structurally fixed unless the Constitution is amended.
A future House redistribution could materially narrow or widen Alberta's population-to-seat gap. A constitutional amendment changing Senate allocation would change the Senate assessment. Neither would alter the distinction between population proportionality and legal entitlement under the rules in force at a given time.

Short answer
Yes, if the benchmark is strict representation by population. Alberta has about 10.8% of House seats versus roughly 11.5% of Canada's 2021 population, and only about 5.7% of Senate seats. But the two chambers are designed differently: the House uses a population-based formula modified by constitutional protections for smaller provinces, while the Senate is explicitly structured around regional representation rather than population.

What's true
Alberta has more residents per MP than the national average under the latest House redistribution, and its Senate representation is much further below its population share. In the House, Alberta has 37 of 343 seats; in the Senate, it has six of 105. On a one-person-one-seat benchmark, the province is underrepresented in both chambers, particularly the Senate.
What's important to qualify
Underrepresentation by population is not the same as being denied seats that Alberta is legally entitled to. The House formula includes constitutional protections for smaller provinces, while the Senate follows a different constitutional design entirely: seats are assigned by provinces and historic regional groupings rather than redistributed according to population growth.
What the evidence shows
Under the 2023 representation order, Alberta has 37 of 343 House seats, about 10.8% of the chamber. Alberta's 2021 census population was about 11.5% of Canada's population, so it is modestly underrepresented relative to strict population share. The House, however, does not use pure proportionality: constitutional rules such as the senatorial clause, grandfather clause and representation rule protect some smaller provinces from losing representation.
The Senate disparity is much larger. Alberta has six of 105 Senate seats, about 5.7%, while accounting for roughly 11.5% of the 2021 population. That is clear underrepresentation by a population benchmark. But population is not the Senate's governing principle. The chamber was structured around provincial and regional representation, with the four western provinces receiving six seats each. Alberta's current Senate allocation is therefore constitutionally prescribed rather than the product of an ordinary redistribution error.
The combined conclusion is that Alberta's population-based representation grievance is real in both chambers, but the institutional explanation—and therefore the path to change—is different in each one.
What remains uncertain
The answer depends on the benchmark. Alberta is underrepresented relative to strict population proportionality, but both chambers are operating according to the constitutional formulas that govern them. Future House redistributions and population shifts can change the House gap; the Senate gap is far more structurally fixed unless the Constitution is amended.
What would change our conclusion
A future House redistribution could materially narrow or widen Alberta's population-to-seat gap. A constitutional amendment changing Senate allocation would change the Senate assessment. Neither would alter the distinction between population proportionality and legal entitlement under the rules in force at a given time.
Why it matters to Canadians
The representation grievance is factually real under a population benchmark, but combining the House and Senate shows why the remedy is not one simple seat count: the two chambers embody different constitutional compromises.
