Quick summary: by early November, a Canadian clinic should have a six-to-eight-week buffer of masks, gloves, disinfectant wipes, hand sanitizer, and tissue on the shelf. Flu season demand builds faster than most supply chains can react, so order before the rush.
Canadian flu season runs roughly November to March, with activity usually peaking in January. For a clinic, that means months of heavier patient volume and a steady draw on the same consumables every day. Below: what to stock, how much to hold, and when to order.
Why Flu Season Is a Supply Problem, Not Just a Health Problem
Flu season is predictable in timing and in its effect on medical supply chains. Demand for masks, gloves, wipes, and sanitizer climbs across the country at the same time, from November through March. When thousands of clinics, pharmacies, and long-term care homes order in the same weeks, suppliers backorder and distributors ration.
In September, a mask order might ship in two days. In January, the same order can sit for weeks. That gap between clinical need and delivery time is why supply planning happens ahead of the season.
The Flu Season Supply Checklist
Work through this clinic supply checklist before November and confirm each line against your own usage. Mark off what you have, order what you do not.
Masks
- ☐ ASTM Level 1 procedural masks for general patient contact
- ☐ ASTM Level 3 masks for aerosol-generating procedures, where higher fluid resistance matters
- ☐ Individually wrapped surgical masks for exam rooms and flu shot stations
Gloves
- ☐ Nitrile exam gloves, 4–5 mil, for routine exams and immunizations
Hand hygiene
- ☐ Foam hand sanitizer at every point of care and checkout
- ☐ Alcohol prep pads for injection sites and minor procedures
Surface disinfection
- ☐ disinfectant wipes and surface cleaners, DIN registered with Health Canada, for exam tables and high-touch points
Patient care
- ☐ Gauze and cotton swabs for wound care and specimen collection
- ☐ Thermometers, plus probe covers if you use electronic units
Staff protection
- ☐ Face shields for procedures with splash risk
- ☐ Isolation gowns for contact precautions and flu-like presentations
- ☐ Bouffant caps where hair coverage is required
How Much to Stock: The 6–8 Week Buffer Rule
The number that works for most Canadian clinics is a six-to-eight-week buffer of everything you use daily. The math is simple: estimate daily consumption per exam room, multiply by clinic days per week, then multiply by seven.
Example: a room using 40 masks a day, five days a week, needs roughly 1,400 masks for a seven-week buffer. Run the same calculation for gloves, wipes, and sanitizer, then add a cushion for flu shot clinic days.
Six to eight weeks is not a regulator’s rule — just a practical buffer that absorbs distributor backorders and the holiday shipping slowdown without filling your storage room with inventory that expires.
Where Flu Season Supply Shortages Happen
Not every item backorders at the same rate. Masks and disinfectant wipes are historically the first to disappear — high-usage items with the thinnest distributor margins. Gloves follow, especially in the 4–5 mil range clinics prefer.
Hand sanitizer and prep pads hold out longer, but they are not immune. If masks and wipes start running short in your region, treat it as an early signal and order gloves and sanitizer at the same time.
Choosing a supplier who carries stock in Canada — and who tells you honestly when something is backordered — makes this easier. See our guide on choosing a reliable PPE supplier for your facility.
When to Order for Flu Season
Order between August and September — before the distributor holiday rush, before flu activity picks up, and before manufacturers start allocating production to their largest accounts. August and September orders typically ship normally; November and December orders compete with every other facility in the country.

Frequently Asked Questions
When should a Canadian clinic start stocking flu season supplies?
Plan your orders for August or September. By early November, aim to have your six-to-eight-week buffer in place.
How many masks should a clinic keep on hand for flu season?
Work from your own usage: daily masks per exam room, times clinic days per week, times seven weeks. That usually lands between a few hundred and a few thousand masks per room.
What is the difference between ASTM Level 1 and Level 3 masks?
Both are tested under ASTM F2100. Level 1 suits general, low-fluid use. Level 3 offers higher fluid resistance and is the usual choice for aerosol-generating procedures.
Do disinfectant wipes and hand sanitizers need regulatory numbers in Canada?
Yes. Disinfectants used in medical settings carry a DIN, and hand sanitizers carry an NPN as registered natural health products. Check both labels before buying in volume.
Do long-term care homes need a different flu season supply plan?
LTC homes follow provincial outbreak protocols, such as Ontario’s IPAC standards, which can trigger extra PPE requirements during an outbreak. If you supply a home, keep additional masks, gowns, and wipes beyond the clinic baseline.
