The dial is mounted on a stainless steel cube with an engraved Equation of Time correction table on the four sides of the cube. The sundial is dedicated to those age 80 an older who have skied at the Oster Bluff Ski Resort.

Dundas Ontario Canada Point in Space Dial 697
A 38 inch diameter porcelain on steel vertical dial declining 14.73? west of east with a point-in-space or nodus gnomon using a 7/8-inch diameter brass ball nodus. Dial face shows Arabic hour numerals, solstice and equinox seasonal lines and a solar noon mark at 1:19:51 PM. Dial shows DST and is corrected for longitude but no EOT correction is provided. It is not know why the street was named Sundial Crescent but, living there, the owners wanted a sundial.
Guelph Ontario Canada Horizontal Dial 370
On the Sunnyside Estate front entrance is a small horizontal dial on a white pedestal surrounded by a flower garden. The original of this sundial is reputed to be the one that was mounted on the stump of the tree felled by John Galt in his ceremonial founding of Guelph on April 23rd, 1827. The original dial and pedestal were carved from Guelph limestone, and are in very poor condition. They were moved indoors during renovations in 1979. A replica now stands in the original position. See NASS Compendium Vol. 6 No. 3, Sept. 1999.
Halton Hills Ontario Canada Analemmatic Dial 539
A stone analemmatic dial with engraved seasonal dates and brass hour markers. The dial is located in Lucy Maude Montgomery Garden, built to celebrate the author of the Anne of Green Gable stories and who lived in Norval, now known as Halton Hills.
Hamilton Ontario Canada Analemmatic Dial 341
Construction of the dial and garden was supported by the Richard and Jean Ivey Fund of London, Ontario. An analemmatic dial about 25 feet wide with stone markers and metal numbers.
Hamilton Ontario Canada Gnomonic Dial 856
At first glance this appears to be a gnomonic dial with a concrete vertical gnomon about 15 feet tall casting its shadow onto a horizontal dial face about 60 feet in diameter in a slightly irregular pattern at one corner of a grass park. But something is seriously wrong for this to be a working sundial. Gnomonic dials tell time by the tip of their gnomon. The size of the gnomon implies that only several hours around noon in the summer could possibly tell time. We would expect that the gnomon is displaced from the center of the hour lines proportional to the height times tangent of the latitude. But here, the brick hour lines radiate centrally from the gnomon. More interesting, the hour lines (and their Roman numeral hour designation) are separated by a nearly uniform increment of 18 degrees per hour. That is, only five hours marks span from North to East.
Hamilton Ontario Canada Vertical Dial 492
On the outside south wall of the library, about 15 feet above the ground is a vertical dial about one meter square. Dial is declined 18 deg 6 min west. The 1pm and 8pm numbers are missing. The dial is stone with aluminum gnomon and numbers.
Kingston Ontario Canada Horizontal Dial 129
A horizontal dial approximately 18 inches in diameter. Made of iron with a solid triangular gnomon Cast raised lettering, sun face, sea symbol. Hours marked by raised lines only. 7AM-5PM. On a small white plaque at the north of the dial are the words "Man eats his bread and records the hour; but the mills of the gods grind eternal flour." Very appropriate considering the dial rests on an old millstone. Update: as of Nov 1996 this dial no longer exists. The millstone is still there in front of City Hall, but the sundial and plaques are gone. Wrought iron base, supporting a large millstone on which the dial is mounted.
Kingston Ontario Canada Vertical Pillar Dial Dial 450
A square pillar of limestone rocks 4 foot on a side and 15 feet high with a small bowl and sphere on top hold two vertical dials each 2x2 feet. The pillar faces are oriented SE and SW allowing for two declining dials. The dials are of solid brass and have hour lines with Arabic numbers in a modern design belying by the stonework of the pillars. Unfortunately the 14-inch gnomons are bent
London Ontario Canada Helioscope Dial 62
A brass Pilkington-Gibbs heliochronomer aligned to the celestial equator. Rotate the helioscope until the sun shines from the upper hole to the lower plate, then read the time from an accompanying dial. The Pilkington-Gibbs dial includes a patented cam mechanism to adjust for the Equation of Time.
Napanee Ontario Canada Armillary Dial 171

Ottawa Ontario Canada Vertical Dial 127
Two vertical declining dials declining 58.1? west and 31.9? east on adjacent sides of the south corner of the Sisters of Charity of Ottawa Mother House. The western dial is approximately 7x8 feet and the eastern dial is approximately 7x4 feet. The dials are of gray plaster with black painted iron gnomons. The dials decline 58.1? west of south and 31.9? east of south. The western dial has hour lines from 10 AM to 7 PM and the eastern dial has hour lines from 7 AM to 3 PM. These dials predate the use of time zones and show local solar time. Mayall on p. 229; erroneously described this dial as on Mint Tower. LAMIRANDE, E., Elisabeth Bruyere, Foundress of Sisters of Charity of Ottawa, Ottawa, 1995, p. 207, "In the course of the same winter, Fr. Allard had built a double sundial of great dimension on the southwest angle of the house (corner of Bolton and Sussex streets) which, even today, continues to give the correct time, as it did in Mr. Bruyere's time; she greatly appreciated the convenience. The work presupposed an advanced knowledge of mathematics and astronomy. It was the first of its kind in Canada."
Ottawa Ontario Canada Hemisphere Dial 449
This hemispherium dial is a dramatic modern sculpture. The 32 inch quarter hemisphere is carved into the edge of a 40 inch cube of dark granite tilted to conform to its latitude of 45.5° , and set upon a rough concrete pedestal of slightly smaller dimension. The gnomon is a
Ottawa Ontario Canada Calendrical Dial 739
A projection calendrical dial that illuminates the headstone of the Unknown Soldier on Remembrance Day, November 11 at 11:00 AM, commemorating the end of World War I. Remembrance Day is celebrated on the 11th hour of the 11th day of the 11th month of each year. The east-west axis extends to the Peace Tower, while the north-south axis parallels the path of the sun across the building on November 11. The concrete walls, grooved with large offset rectangles, are reminiscent of the rows of white grave markers in Allied war cemeteries. The headstone of the Unknown Soldier is the lone artifact, a simple bench the only furniture in Memorial Hall.
