Heat Loss Calculation Tiny Township
CSA F280 heat loss calculations for Tiny Township building permits at the correct Climate Zone 6 design temperature — BCIN-stamped, accepted by the Township of Tiny Building Department, delivered in 48 hours.
A Tiny Township building permit requires a CSA F280 heat loss calculation at Tiny Township OBC January 2.5% design temperature of -24°C (Supplementary Standard SB-1) — Climate Zone 6. That places Tiny among the colder Zone 6 areas — similar to Barrie (-24°C) and noticeably colder than Toronto and the GTA (-18°C). We deliver a BCIN-stamped report with the MVDS and Schedule 1, formatted for the Township of Tiny Building Department. From $395, in 48 hours.
Tiny Township design temperature: -24°C (Zone 6)
Under OBC 9.33.2.2, your CSA F280 must use Tiny Township official January 2.5% heating design temperature from Supplementary Standard SB-1: -24°C, Climate Zone 6. North Simcoe areas including Tiny Township, Midland and Penetanguishene record one of the colder Zone 6 design temperatures, on par with inland Barrie (-24°C) and well below the Toronto/GTA assumption (-18°C) that contractors often copy. Using the wrong design temperature is the most common reason reports are returned. Check yours with our free design temperature lookup.
| Area | Design Temp | Zone |
|---|---|---|
| Toronto / GTA | -18°C | 5 |
| Collingwood | -21°C | 6 |
| Tiny / Midland / Penetanguishene | -24°C | 6 |
| Muskoka | -26°C | 7 |
What a Tiny Township permit package needs
A complete package includes a CSA F280 heat loss report at -24°C, mechanical drawings, the MVDS ventilation summary (mandatory under OBC 2024), and the Schedule 1 designer declaration — every page BCIN-stamped, formatted for the Township of Tiny Building Department. See our permit requirements guide.
Heat pumps and sizing at -24°C
At Tiny Township -24°C design day, a cold-climate (CCASHP) heat pump typically delivers roughly 55-70% of its rated capacity, so the unit must be checked against the calculated load at -24°C, not the nameplate. Well-insulated homes can run all-electric, but at this design temperature backup heat is often appropriate. The room-by-room CSA F280 at -24°C confirms the right size; see our cold climate heat pump guide.
Heat Loss in Tiny Township — FAQ
What design temperature is used for Tiny Township?
-24°C, the Tiny Township OBC January 2.5% value from SB-1 (Climate Zone 6) — among the colder Zone 6 areas, similar to Barrie (-24°C) and well below Toronto/GTA (-18°C). Midland and Penetanguishene share -24°C.
How much does it cost and how fast?
CSA F280 reports start at $395 flat, BCIN-stamped, quoted within 24 hours and delivered within 48 hours of payment. A full HVAC design package starts at $695.
Can a cold-climate heat pump heat a Tiny Township home?
Yes for well-insulated homes — but at -24°C a CCASHP delivers roughly 55-70% of rated capacity, so output must be checked against the CSA F280 load and backup heat is often appropriate.
Do Midland and Penetanguishene use the same value?
Yes — Midland and Penetanguishene use the same -24°C Zone 6 design temperature as Tiny Township.

Tiny Township runs along the Georgian Bay beaches from Wasaga to Penetanguishene, and it uses the same -24 C design temperature as Midland. It is also home to thousands of seasonal cottages, and more of them become year-round homes every year.
A cottage conversion needs a building permit, and the permit needs a heat loss. That calculation shows whether the walls, floor and roof can be heated at a sane cost, or whether the envelope has to be upgraded first. Better to know before you buy equipment.
We know Tiny well. Our own ICF showhome is here, and it heats for about $100 a month at the coldest. Many Tiny lots are off the gas line, so we design for heat pumps, propane, or both.
What to send us

Why the right inputs matter
The heat loss sets the size of your furnace, heat pump or boiler, and the size of every duct or loop. If the inputs are guessed, everything after it is a guess too. Too big wastes money and short-cycles. Too small leaves cold rooms on the coldest nights. Get the inputs right once and the rest of the job follows.
