Canada will see a partial solar eclipse when the annular solar eclipse on October 14, 2023, traverses the narrow path on land from Oregon in the U.S. to the coast of Natal in Brazil.
Depending on where you are located in Canada, you can view up to 85% obscuration of the sun during the partial Solar Eclipse, which means there will be noticeable darkening of the day (at those locations).

Time and Duration of Solar Eclipse in Canada
Unlike a total solar eclipse, where the moon entirely obscures the sun, an annular eclipse results in a bright “ring of fire” around the moon. This occurs because the moon, positioned at its farthest from Earth, appears smaller, not fully covering the sun.
The full annular spectacle is only visible from locations along the path of annularity, where the moon crosses the sun’s center. Observers in Western Canada can anticipate a partial eclipse with more than 50% of the sun’s area covered by the moon.

How & Where to View Solar Eclipse
If the sky is clear (not cloudy) and if you are in the path of the partial eclipse, you can view the eclipse by looking at the sun during the time of the eclipse from a location of your choosing through special solar filters specially made for the purpose of viewing a solar eclipse.
Remember, it is not safe to view the Sun without appropriate filters.
Ensure you buy genuine glasses through local RASC/Science Centres or reputable stores. Select RASC chapters have distributed solar glasses to the local library. Check with your local chapter/library.
Where to Buy Solar Eclipse Glasses:
- Local RASC/Science Centres.
- List of reputed vendors by NASA
Other Options:
- Do a science project and make a pinhole projector – How to make a pinhole projector.
- Welder’s Mask – A welding mask with a lens rating of 14 (ONLY THAT) is safe for viewing the eclipse. Do not use a welder’s mask if the lens is damaged or scratched or if the shade rating is unknown.

Eclipse Viewing Events in Canada – Saturday, October 14, 2023
Many viewing parties (weather dependent) are organized in Canada by regional RASC centres, science centres and various university physics departments. Solar Telescopes will be set up on the grounds at most locations, and free eclipse glasses will be distributed at most venues (while supplies last).
