Ottawa Ontario Canada Horizontal Dial 230
A large horizontal floral dial approximately 20 feet in diameter. Large circular area on ground forming the dial face with gravel and flower-beds between the hour lines. The flowers are annuals, best seen in the summer blooming season. Update Nov 1996: The dial is still there, but the flower beds are gone. Update 2016: flower beds are back, but the pipe gnomon is badly bent. The gnomon angle at the bottom is correct, but the pipe section is bent and off axis.
Scarborough Ontario Canada Equatorial Dial 790
A 45 inch diameter bronze equatorial ring dial with an arrow-pointed rod gnomon. The dial is mounted atop a 36 inch square pink granite plinth with chamfered corners sitting on a concrete base.
Stouffville Ontario Canada Vertical Dial 730
A 46 inch wide by 52 inch high south-facing vertical dial of high density urethane with a 10 mm diameter stainless steel gnomon. Dial face has hour lines with half-hour marks and Roman numerals. Hour lines are longitude corrected. A brass plaque containing the dedication, additional information about reading the dial and an equation of time table is mounted on the building wall below the dial. An informative booklet about church sundials is available in the church.
Stouffville Ontario Canada Vertical Dial 751
A 42 x 72 inch, 10 inch thick, 3300 pound black granite vertical dial on a 5 foot high steel tube pedestal. Gnomon is a 5/16-inch stainless steel shaft with a dowel-type nodus to mark solar declination. Dial shows EDST with longitude correction. Dial face includes hour and half-hour lines, and equinox and winter and summer declination lines. Dial center is the pivot of the compasses in the Masonic Square and Compass emblem, with oak leaves. Below the dial is a 12 x 72 inch oak plaque inscribed with dedication information and two brass plaques with dial information and EOT graph.
Sudbury Ontario Canada Terra Globe Dial 359
A monumental dial in stainless steel. At one end of 'Polaris Boulevard' which includes Terra, a segment of the globe oriented with Sudbury directly at the top. Celeste is a giant (12.8 meter or 42-foot) stainless steel sundial located at the south end of Polaris Boulevard. It consists of two arches, one which represents the equator in the sky, and one which represents the meridian, or the line from the North Pole to South Pole. A large steel pipe makes up the gnomon of the sundial.
Thunder Bay Ontario Canada Analemmatic Dial 466
A very well constructed analemmatic dial about 24 by 11 feet. The dial may be difficult to find, since it is in the center of a field that is devoted to wild grass of the area. Cement markers are used to show the hours and for the central base showing the months where to stand. The hourly markers are corrected for the longitude of Thunder Bay. The site is visited quite frequently by school children and is a great educational tool for dialing.
Toronto Ontario Canada Horizontal Dial 596
A 210 cm diameter horizontal dial of blue granite with a 56 cm high stainless steel gnomon. In addition to showing local time, the declination line that touches the base of the gnomon traces the path of the shadow on June 23 (date of the 1985 Air India terrorist-bomb air crash) and also marks solar noon at the crash site near Akahista, Ireland where there is a similar memorial sundial. Stones forming the pedestal represent all of the Provinces and territories of Canada, and the countries of India, Ireland, Japan and the United States of America.
Toronto Ontario Canada Equatorial Dial 364
The face of this equatorial dial is an arc of a sphere 2 meters in diameter. A nodus on the polar gnomon casts a shadow indicating solar declination. Aligned with the dial is a 15 meter meridian line which passes through the site of the transit instrument of the former Toronto Observatory.
Toronto Ontario Canada Horizontal Dial 128
Approx 55 ft square Stone (concrete?) 4AM-8PM marked in Arabic numerals, half and quarter hours marked with lines. A huge dial. The gnomon is sunk below the outer level by a series of steps. The hours are marked by stone slab 'seats' spaced around the outer square. There are two seats at the noon position to allow for the width of the gnomon. This dial may have been destroyed by now in a rebuilding project.
Toronto Ontario Canada Armillary Dial 413
Armillary dial about 4 foot in diameter. Gnomon rod appears to be missing. Raised Roman numbers show the hours from V in the morning to VII at night. Equatorial strip is about 6 inches wide.
Toronto Ontario Canada Equatorial Dial 414
An equatorial dial with rod gnomon bent into a half analemma. Raised Roman numerals along the equatorial arc from V in morning to VII at night. Gnomon held by semi-circular arc with pleasing proportions that match the equatorial arc.
Toronto Ontario Canada Horizontal Dial 433
A striking 30 inch diameter horizontal dial. The equation of time correction is made by a slight rocking of the gnomon about the polar axis, controlled by a manual date index and a hidden cam mechanism. At the south end of the gnomon on the dial is a sunburst design. The octagonal pedestal is ornately covered with six copper plates. Each showing two zodiac signs in relief, forming a frieze 20 inches high around the pedestal.
Toronto Ontario Canada Horizontal Dial 435
A small bronze 8 inch diameter horizontal dial, sitting upon a granite column of equal diameter. The dial plate has simple radiating hour lines and Roman numerals. No minute or quarter hour marks. The gnomon may have broken off at some time and been repaired, since it is now held on by a rather unsightly bronze angle iron.
Windsor Ontario Canada Noon Mark Dial 779
A 12 foot high noon mark dial consisting of two closely spaced triangular vertical plates, a protruding needle and pairs of summer and winter solstice "wings" that together project a shadow onto the surrounding concrete deck within a 40 foot diameter reflecting pool. When the sun totally illuminates the narrow space between the vertical plates, it is local noon and the shadow cast by the protruding needle points true north. On the summer solstice, the shadow cast by the smaller, upper solstice wings will be at its narrowest width. On the winter solstice, the shadow cast by the lower solstice wings will be at its narrowest width.
Windsor Ontario Canada Armillary Dial 780
A simple armillary dial about two feet in diameter with an equatorial hour ring. The dial is mounted atop a tall, black cylindrical pillar within a formal garden of Willistead Manor. The manor is open to the public on selected days.
Windsor Ontario Canada Vertical Dial 874
A vertical stone sundial made of white quartzite approximately in a 6 x 4 feet rectangle. The dial face includes engraved hour lines from 7am to 6pm in Arabic hour numerals for Eastern Daylight Time and an elegant engraved outline of St. Dimitrije based on a partially preserved 14th century fresco of the Saint in St.Mary's Church, Donja Kamenica, Serbia. Rather than summer and winter solstice lines, a single hyperbola indicates the route of the gnomon shadow's tip on 8 November - the day of St.Demetrius (St. Dimitrije). In fact, the gnomon is represented at St. Demetrius' sword (or more appropriately, his spear). A small bell is engraved at 10am indicating the time of morning liturgy. At about 11:15 if you look closely, you can see the subnode point (polos montaza) of the gnomon tip used for alignment during construction.
Windsor Ontario Canada Vertical Dial 639
Two vertical bronze-on-masonry dials on adjacent faces upper faces of a square, 25 foot high tower. Dial faces are aligned approximately SE and SW. A bronze armillary sphere is placed atop the tower. The tower and sundials were designed and built by the Windsor Polish community and dedicated in the Windsor centennial year in memory of M. Kopernik (Copernicus).
