The plumbing supply calendar: planning marketing around Canada's seasons

How to build your own calendar first

Before you use any generic calendar, including this one, pull two years of sales by category and branch, month by month. Look for:

1. Peaks: the months when each category sells most.
2. Ramp-up: how many weeks before the peak sales start climbing.
3. Stock-outs: when you ran out, which tells you where planning failed.
4. Branch differences: a coastal branch and an inland branch may peak weeks apart.

Then set each campaign to start six to eight weeks before the ramp-up. That gives purchasing time to stock and gives plumbers time to hear the message before they're busy.

Late summer: plan the heating season

What's happening: finish work on summer renovations, new-build finish stages, and the quiet before the fall rush.

What to plan now:

• Heating-season stock for water heaters, boilers, hydronic parts and venting
• Freeze protection: heat tape, pipe insulation, frost-free hose bibs
• Showroom programs for fall and winter renovations
• Consent-based reminders to accounts about fall stocking

This is the most underused window in plumbing supply marketing. Plumbers have a little more time to talk, and suppliers who use it start the fall with a head start.

Fall: heating season begins

What's happening: heating systems start running, and with them water heater failures, boiler service calls and the first freeze-ups in colder regions.

What to promote:

• Replacement water heaters and boilers, with clear catalogue pages on sizing and venting
• Hydronic components and repair parts
• Counter hours, will-call and delivery options
• Any current utility program relevant to your products, with a date and link

For example, as of October 2026 the SaskEnergy equipment replacement rebate lists amounts for condensing and tankless water heaters, boilers and combi boilers. A dated explainer that plumbers can send to homeowners helps close replacement jobs. Always confirm current terms with the administrator, because programs change.

Deep winter: freeze-ups and failures

What's happening: frozen and burst pipes, failed water heaters and emergency calls. In many regions this is the most urgent counter trade of the year.

What to promote:

• Repair fittings, couplings and pipe repair products
• Pipe thawing equipment
• Extended or early counter hours and after-hours pickup, if you offer them
• Branch stock of high-demand emergency items

Key point: the marketing for this season should have happened in the fall. In deep winter, the job is to keep listings accurate (especially hours during storms) and to remind consenting accounts what you have in stock.

Late winter and spring thaw: water where it shouldn't be

What's happening: snowmelt and spring rain bring basement water, sump failures and drainage work. On the Prairies and in many inland areas, the thaw can be sudden.

What to promote, starting in late winter:

• Sump pumps and battery backups
• Backwater valves and drainage products
• Sewage and effluent pumps
• Plain-language content plumbers can share with homeowners about protecting basements

If you sell into Quebec, note that the province's Rénoclimat program added a flood-adaptation stream in 2026. Read the official details before mentioning it, and see the Quebec page.

Spring into summer: construction season

What's happening: rough-in and finish volumes peak on new builds, and renovation work is in full swing. Project desks are busiest.

What to promote:

• Rough-in packages: PEX, copper, ABS and PVC DWV, fittings and valves
• Delivery to site and early counter hours
• Project desk quote turnaround and submittal documents
• Builder and mechanical contractor programs

This is the season for project desk marketing. Quote follow-up matters most when every estimator is juggling several tenders.

Regional differences that change the dates

The calendar shifts across Canada:

• Southwest BC coast: milder winters, so freeze-ups are occasional spikes rather than a season; wet-season drainage matters more. See British Columbia.
• Prairies: long, cold winters and a compressed building season. Fall campaigns need to start early, and project desks must move fast in spring.
• Central Canada: a longer building season in the south, with the North behaving more like the Prairies.
• Atlantic Canada: frequent freeze-thaw cycles and a heating mix where oil and heat pumps matter. Conversion programs such as the takeCHARGE oil-to-electric incentive in Newfoundland and Labrador can create steady plumbing work.
• The North: freight windows, including sealift and winter roads, set ordering deadlines months ahead. See the territories page.

A worked example

Take a supplier with three branches: one in a coastal city, one inland and one in a northern town. A single national campaign launched on November 1 would be early for the coast, about right inland and far too late for the north, where heating-season orders may already have shipped.

With branch-level calendars, the northern branch sends ordering reminders in late summer, the inland branch launches its heating campaign in September, and the coastal branch focuses on fall drainage and a shorter freeze-protection push in November. The budget is the same; the timing fits each market.

A planning checklist for each season

For every seasonal campaign, confirm:

1. Dates: campaign start set six to eight weeks before the branch's ramp-up.
2. Stock: purchasing has confirmed quantities for every promoted product.
3. Listings: seasonal hours and services updated on every branch profile.
4. Catalogue: pages for promoted categories are accurate and show how to reach a branch.
5. Consent: reminders go only to accounts that have agreed to receive them.
6. Programs: any rebate mention is dated, linked and checked with the administrator.
7. Measures: category sales by branch, new accounts and stock-outs, compared with last year.

Common mistakes

• Launching campaigns when the weather turns, rather than before.
• Promoting products that aren't in stock at the branches being advertised.
• Using one national date for every branch.
• Leaving last season's promotions and closed rebates on the website.
• Forgetting to update branch hours during storms and holidays.
