The Tax Deadline That Has Everyone Thinking Creatively
With April 30 looming on the calendar, Canadians coast to coast are doing the annual scramble — digging up receipts, hunting for deductions, and dreaming of any loophole that might shrink this year's bill. But long before TurboTax and RRSP contribution rooms, some Newfoundlanders may have found a much more literal solution: they built it right into their homes.
Enter the 'mother-in-law door' — one of Atlantic Canada's most enduring architectural mysteries.
What Exactly Is a Mother-in-Law Door?
If you've ever walked through the older neighbourhoods of St. John's or any number of outport communities in Newfoundland and Labrador, you've probably noticed it: houses with two front doors, side by side, opening onto the same porch or step. To an outsider, it looks like a duplex. But open both doors and you'll often find a single, unified family home inside.
Locals have been calling these 'mother-in-law doors' for generations — the folk explanation being that the second entrance was added for an in-law suite or an elderly relative who needed their own private entry. It's a charming story, and in many cases, probably true.
But there's another explanation that's gained traction over the years, and it has everything to do with taxes.
The Tax Avoidance Theory
The theory goes like this: in earlier eras of property taxation, a home's tax assessment was sometimes tied to the number of entrances — or more specifically, to whether a building appeared to be a single-family dwelling versus a multi-unit property. By adding a second front door, homeowners could potentially classify their home differently, or at least muddy the waters enough to reduce what they owed.
Whether this was ever a widespread, deliberate strategy — or simply a post-hoc explanation for a practical architectural tradition — is a matter of some debate among historians and locals alike. The CBC has revisited the legend ahead of this year's tax deadline, noting that the origin story remains genuinely murky.
A Quirk That Says Something About Canadian Resourcefulness
What makes the mother-in-law door legend so compelling isn't just the tax angle — it's what it says about the relationship Canadians have always had with government, money, and making do. Newfoundlanders, who didn't join Confederation until 1949, developed their own distinct ways of navigating colonial-era taxation and property rules. Creative workarounds weren't just clever; they were sometimes survival.
And frankly, as anyone staring down a tax bill this week can attest, the impulse to find every legal edge hasn't gone anywhere.
Still Standing
Today, mother-in-law doors are considered a heritage feature in many NL communities — a piece of vernacular architecture that tells the story of the province's past. Whether they started as a tax strategy, a practical accommodation for extended families, or simply a regional aesthetic preference, they've become part of Newfoundland's visual identity.
So as you file your return before the April 30 deadline, take a moment to appreciate that Canadians have always been creative when it comes to taxes. Some just expressed it in brick and mortar.
