Back to School: What the September Traffic Spike Reveals

Every year, the same thing happens: by late August, traffic picks up for a large share of Canadian retailers, without any extraordinary advertising needed to trigger it. Back-to-school is one of those rare moments when demand shows up almost on its own — provided you’re ready to meet it.

This spike isn’t just a seasonal footnote. It reveals specific buying behaviours that stay useful well beyond September — whether you run a permanent liquidation centre or organize a one-time sale.

Why does back-to-school create a predictable traffic spike every year?

What sets back-to-school apart from other seasonal peaks is its regularity. Families know they’ll need to shop, they know roughly when, and they know roughly what for. That level of predictability is rare: most consumption spikes depend on an external trigger (particular weather, an aggressive promotion, a trend that takes off), whereas back-to-school arrives almost out of obligation.

For a retailer, this predictability is a rare opportunity to plan ahead rather than react. It’s also why back-to-school benefits one-time sales and permanent retailers alike: the demand exists independently of how it’s captured.

Which product categories benefit most from back-to-school?

The most obvious effect touches children’s clothing and footwear: it’s the category most directly tied to the school calendar, and the one where purchases are the least deferrable. Next comes anything related to organization — backpacks, supplies, storage — where families look for functionality as much as price.

A less obvious, but very real phenomenon: back-to-school also triggers a broader renewal instinct at home. Once in a preparation mindset, many consumers take the opportunity to replace other items that had been sitting on their list for a while — which explains why categories that seem, at first glance, unrelated to school also see their traffic rise in September.

Do a permanent liquidation centre and a one-time sale benefit from back-to-school the same way?

For a one-time sale, back-to-school is a window not to be missed: the calendar is tight, and most of the success depends on being visible at the right moment, with the right products already featured.

For a permanent liquidation centre, back-to-school isn’t a single event, but a period that’s prepared for in advance and continues past the official date. Families who missed the bulk of their shopping in late August often keep completing their list into September — a natural advantage for a retailer that stays open and visible well beyond the first day of school itself.

How far ahead do shoppers start their back-to-school shopping?

Statistics Canada publishes monthly retail sales data precisely because these cycles repeat from year to year, with variations by product category. Back-to-school illustrates this well: the increase doesn’t happen all at once, it builds gradually as the date approaches.

For a retailer, that means waiting until the last week of August to become visible means missing part of the wave. Our article How to Create Anticipation Around Your Sales covers this principle in more depth: the earlier an offer is announced, the better its chances of reaching shoppers who are already planning.

What lessons from back-to-school apply to other seasonal peaks?

What makes back-to-school particularly instructive is its clarity: the trigger is known, the date is fixed, and the product categories involved are easy to identify. It’s a textbook case for observing how a demand spike actually behaves — and for carrying those observations over to the other strong moments of the year, where the same principle applies even when the trigger is different.

Our article Why Your Warehouse Sales Lack Traffic covers several of the same principles applied to a different context. And if your business thrives on this kind of year-round presence rather than a single peak, our article Liquidation Centre: Thinking About Year-Round Visibility explores that angle further.
