Upper Joshua Creek

Upper Joshua Creek is Mattamy Homes’ community in North Oakville, between Sixth Line and Ninth Line north of Dundas Street East, and every home in it is heated and cooled by geothermal energy. Mattamy is selling homes in Phases 6B, 6C and 6D: quick move-in townhomes and detached homes, a few of them ready now and most closing in the first half of 2027, “pre-design” detached homes with some upgrades already chosen, and four single-car lots to build on. All are ENERGY STAR® certified, and the Phase 6B homes are also Net Zero Ready.

Quick move-in townhomes

Mattamy’s November 3 townhome package has four freehold two-storey quick move-in townhomes, each with four bedrooms, 2.5 baths and a single-car garage: a Laurel (1,717 sq ft) that Mattamy lists for December 2026, and a Mint End (1,938 sq ft) and two Shamrock Ends (2,316 sq ft) closing in March 2027. Mattamy takes $20,000 off and includes their design upgrades, so prices start at $1,051,990 with HST, and it shows $952,204 for the Laurel after the 2026 HST relief for qualifying buyers.

Detached homes

The detached homes come in three sizes: 34-ft lots with a single-car garage (the Barnett, Coxland, Giddings, Rosebank, Reign and Shaw Wood, 2,010 to 2,758 sq ft), 38-ft lots with a double-car garage (the Brookdale Corner, Chisholm, Thorncliffe, Windfield and 2.5-storey Kingsley, 2,546 to 3,179 sq ft) and, in Phase 6B, 45-ft deluxe lots with a double-car garage (the Beauford, Fairbank and Ryland, 3,334 to 3,728 sq ft). Mattamy takes $40,000 off the single-car homes and $50,000 off the double-car homes, with a $20,000 Design Studio credit, and $100,000 off the 45-ft homes. The Rosebank, Windfield and Kingsley are its model homes.

Quick move-in and pre-design homes

Most of what Mattamy is selling here is already under way. Its November 3 to 5 lists have 21 detached quick move-in homes, with upgrades worth $31,775 to $69,334 included, and 19 pre-design homes, where Mattamy has already chosen some upgrades, such as a third bath or a 4-bedroom plan, worth $10,990 to $35,075. With HST and Mattamy’s discount, they start at $1,296,990 for a Barnett, $1,565,990 for a Chisholm and $2,050,990 for a Fairbank, and closings run from ready now to June 2027. Phase 6D also has four single-car lots to build on, closing in July 2027, where you choose the design and elevation.

The site plans

Mattamy’s Phase 6D plan shows detached homes on Bronwyn Road, Farley Street and John McKay Boulevard, beside the natural heritage system, and townhome blocks on William Cutmore Boulevard, near a future separate elementary school, a neighbourhood park and a village square. Its key map puts the community between Sixth Line and Ninth Line, north of Dundas Street East and south of Burnhamthorpe Road East. Open the Phase 6C and Phase 6B plans too.

Geothermal, ENERGY STAR® and Net Zero Ready

Every home is heated and cooled by a ground source heat pump connected to a geothermal system, and there is no natural gas in the community. Mattamy’s agreement says the geothermal infrastructure is supplied by Fernsby Geothermal under a separate energy service agreement, and that its heating and cooling rates are not regulated by the Ontario Energy Board. Mattamy’s townhome specifications also list an energy recovery ventilator, R60 attic insulation, spray foam over the garage, high-efficiency windows, a smart thermostat, LED lighting and a third-party inspection and airtightness test. The Phase 6B homes are Net Zero Ready, which Mattamy defines by the Canadian Home Builders’ Association standard.
