Georgian Bay Township design temperature: -24°C (Zone 7)
Under OBC 9.33.2.2, your CSA F280 must use Georgian Bay Township official January 2.5% heating design temperature from Supplementary Standard SB-1: -24°C, Climate Zone 7. Georgian Bay Township (Honey Harbour and the surrounding shoreline and islands) is in Climate Zone 7, with a design temperature of -24°C — similar to Parry Sound (-24°C) and a touch milder than inland Muskoka (-26°C). It is far colder than the Toronto/GTA assumption (-18°C) that contractors often copy. Using the wrong design temperature is the most common reason reports are returned.

Heat pumps and sizing at -24°C
At Georgian Bay 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 Georgian Bay Township — FAQ
What design temperature is used for Georgian Bay Township?
-24°C, the OBC January 2.5% value from SB-1 (Climate Zone 7) — similar to Parry Sound (-24°C), a touch milder than inland Muskoka (-26°C), and well below Toronto/GTA (-18°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 Georgian Bay 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 usually appropriate, particularly for off-grid or island properties.
Do island and waterfront builds differ?
The design temperature is the same (-24°C, Zone 7), but island and off-grid builds often weigh backup heat and fuel logistics more heavily. The CSA F280 load is the starting point for those decisions.
