Canada can’t have fast population growth, housing supply constraints, and housing affordability

From the MacDonald Laurier Institute
By Steve Lafleur
No one wants to solve the housing crisis enough to make the hard choices.
It’s tempting to try to have it all and policymakers are not immune to this. There are tradeoffs in everything. Ignoring those tradeoffs might work for awhile, but eventually reality catches up to you. Try as we might, we can’t have it all.
For instance, we can’t have rapid population growth, housing supply constraints, and housing affordability all at the same time. We’ll call this the housing affordability trilemma.
The idea of a policy trilemma comes from the Mundell-Fleming model which is included in most introductory economics textbooks. The model was named after Canadian economist Robert Mundell and British economist Marcus Fleming, who developed the idea in the early 1960s. The basic premise of the model, also called the “impossible trinity” or “trilemma” is that you can have two of three policies, but not all three (namely, free capital flow, a fixed exchange rate, and a sovereign monetary policy).
The idea of an impossible trinity can and has been applied to other situations, like the euro crisis in the early 2010s, and provides a useful way of looking at seemingly intractable problems. Plotting the related problems on a Venn Diagram helps visualize the problem. Here is the Mundell-Flemming model, visualized.

Now, let’s return to housing policy. Few Canadian problems are as intractable as the now nationwide housing affordability crisis. Rents are rising quickly, apartment availability is falling, and home prices are the highest relative to incomes in the G7. As we’ve shown in a recent paper for the MacDonald Laurier Institute, Canada’s population growth is outstripping housing growth. This, unsurprisingly, has undermined housing affordability. Let’s visualize this trilemma.

At the root of Canada’s housing woes is a severe shortage of homes relative to the number needed. We simply don’t build enough homes to adequately house current and future Canadians.
Not only is there cross-party consensus that there’s a housing shortage, but most parties in provincial and federal elections have proposed policies aimed at addressing it. So why do we still have a shortage?
Let’s go through the elements of the Canada’s housing trilemma (or housing impossibility trinity).
The first element is a fast-growing population. Canada has the fastest growing population in the G7, and last year alone grew by more than a million people. Barring any major shifts in immigration policy, this trend is unlikely to change any time soon. Indeed, the population grew by 430,635 in the third quarter of 2023. That’s the highest quarterly growth rate since 1957.
The second element is restrictions on homebuilding. Whether intended or not, a suite of policies processes and regulations that prevent or limit the addition of more homes both in existing neighbourhoods and at the urban fringe. Barriers to density include local zoning bylaws, lengthy and uncertain consultation processes, and growth plans that exclude building or upgrading the infrastructure necessary to enable more homebuilding in existing neighbourhoods. Policies explicitly preventing the addition of homes outside of existing neighbourhoods include Ontario’s Greenbelt and British Columbia’s Agricultural Land Reserve, while softer versions include local planning targets limiting the share of development slotted to occur on city outskirts. Given these limitations, it’s no surprise that we’ve rarely surpassed 200,000 housing completions annually since the 1970s, while the rate of population growth has reached generational highs.
The third element is housing affordability. That is, the ability for individuals and families earning local incomes to comfortably meet their housing needs. This means shelter costs don’t prevent them from feeding and clothing themselves, but also allow saving and investing in an education, for instance. For example, some peg the cut-off for affordability at 30 percent of income. By that measure, a household would require an income of over $100,000 to afford a one-bedroom apartment in Vancouver, for example.
Whether we like it or not, we can’t have fast population growth, rigid housing supply constraints, and housing affordability all at the same time.
For most of our recent past, the choice we’ve collectively made is to accelerate population growth while maintaining many (if not most) restrictions on both outward and upward growth, meaning we’ve excluded the possibility of achieving broad affordability. The consequences? All the symptoms mentioned before: rising rents, falling vacancies, higher ownership costs.
Despite recent pivots by a growing number of local and provincial governments, the balance of housing and land-use policies remains firmly tilted against reaching the level of homebuilding we need to restore some semblance of affordability, which by some estimates means more than doubling homebuilding. To wit, housing construction has remained remarkably stagnant—even slightly declining—in recent decades. Even the bold changes to zoning recently passed in British Columbia, Ontario and Nova Scotia are unlikely to double the number of housing built provincewide.
But, as the housing trilemma suggests, there are alternative routes. If Canadians remain adamant about affordability, we can demand more meaningful reduction or removal of policies preventing a growth in housing supply, or we can demand a reduction in population growth, or both. These are not easy choices but ignoring them doesn’t make them go away. We need to build upwards, outwards, or both, in order to meaningfully increase housing production. We can’t say no to every solution and expect better results.
The point is, there’s broad consensus that Canada faces a housing crisis, and that major policy actions are needed to fix the problem. There’s also a tacit consensus that the policies feeding the crisis should remain in place.
To put it more bluntly, everyone wants to solve the housing crisis, but no one wants to solve the housing crisis enough to make the hard choices. Until we collectively shift our priorities, we are choosing to sacrifice housing affordability. We can’t have it all. If we insist on maintaining fast population growth and restrictions on supply, we’ll get the broken housing market we deserve.

Saskatchewan becomes first Canadian province to fully eliminate carbon tax

From LifeSiteNews
Saskatchewan has become the first Canadian province to free itself entirely of the carbon tax.
On March 27, Saskatchewan Premier Scott Moe announced the removal of the provincial industrial carbon tax beginning April 1, boosting the province’s industry and making Saskatchewan the first carbon tax free province.
Under Moe’s direction, Saskatchewan has dropped the industrial carbon tax which he says will allow Saskatchewan to thrive under a “tariff environment.”
“I would hope that all of the parties running in the federal election would agree with those objectives and allow the provinces to regulate in this area without imposing the federal backstop,” he continued.
The removal of the tax is estimated to save Saskatchewan residents up to 18 cents a liter in gas prices.
The removal of the tax will take place on April 1, the same day the consumer carbon tax will reduce to 0 percent under Prime Minister Mark Carney’s direction. Notably, Carney did not scrap the carbon tax legislation: he just reduced its current rate to zero. This means it could come back at any time.
Furthermore, while Carney has dropped the consumer carbon tax, he has previously revealed that he wishes to implement a corporation carbon tax, the effects of which many argued would trickle down to all Canadians.
The Saskatchewan Association of Rural Municipalities (SARM) celebrated Moe’s move, noting that the carbon tax was especially difficult on farmers.
“I think the carbon tax has been in place for approximately six years now coming up in April and the cost keeps going up every year,” SARM president Bill Huber said.
“It puts our farming community and our business people in rural municipalities at a competitive disadvantage, having to pay this and compete on the world stage,” he continued.
“We’ve got a carbon tax on power — and that’s going to be gone now — and propane and natural gas and we use them more and more every year, with grain drying and different things in our farming operations,” he explained.
“I know most producers that have grain drying systems have three-phase power. If they haven’t got natural gas, they have propane to fire those dryers. And that cost goes on and on at a high level, and it’s made us more noncompetitive on a world stage,” Huber decalred.
The carbon tax is wildly unpopular and blamed for the rising cost of living throughout Canada. Currently, Canadians living in provinces under the federal carbon pricing scheme pay $80 per tonne.

Fight against carbon taxes not over yet

As the federal government removes the consumer carbon tax, the Canadian Taxpayers Federation is calling on all party leaders to oppose all carbon taxes, including the hidden tax on business.
“Canadians fought hard to force Ottawa to back down on its consumer carbon tax and now the fight moves to stopping the hidden carbon tax on business,” said Franco Terrazzano, CTF Federal Director. “Canadians can’t afford a carbon tax on business that pushes up prices at the gas station and makes it harder for our businesses to compete while they’re already struggling with a trade war.”
Today, the federal government cut the consumer carbon tax rate to $0. This will reduce taxes by about 17 cents per litre of gasoline, 21 cents per litre of diesel and 15 cents per cubic metre of natural gas.
The federal government still imposes an industrial carbon tax on oil and gas, steel and fertilizer businesses, among others.
During the Liberal Party leadership race, Prime Minister Mark Carney said he would “improve and tighten” the industrial carbon tax and “extend the framework to 2035.”
Just 12 per cent of Canadians believe businesses pay most of the cost of the industrial carbon tax, according to a Leger poll commissioned by the CTF. Meanwhile, 70 per cent said businesses would pass most or some carbon tax costs on to consumers.
Conservative Party Leader Pierre Poilievre said he will “repeal the entire carbon tax law, including the tax on Canadian businesses and industries.”
“Carbon taxes on refineries make gas more expensive, carbon taxes on utilities make home heating more expensive and carbon taxes on fertilizer plants increase costs for farmers and that makes groceries more expensive,” Terrazzano said. “Canadians know Poilievre will end all carbon taxes and Canadians know Carney’s carbon tax costs won’t be zero.
“Carney owes Canadians a clear answer: How much will your carbon tax cost?”
