A view through eclipse glasses.You should never look at the Sun without proper protection.  During most of the total solar eclipse, you can only look directly at the Sun if you are using such protection.

For protection when viewing the Sun, you must wear certified solar eclipse glasses that satisfy the ISO 12312-2:2015 safety standard.  Certified glasses are being given out for free by McMaster University to local communities in partnership with libraries. Distribution will begin after February 22 at Hamilton, Norfolk and Haldimand Public Library branches, February 26 at McMaster University libraries, after March 4 at Burlington Public Library branches, Six Nations Public Library and Brantford Public Libraries.  We are also working closely with local school groups. Please complete the contact us form on this page to request complimentary glasses courtesy of McMaster University for organizations or large groups. If you are outside of the Hamilton-Burlington areas and wish to order your glasses, please order from a verified reputable source.

Looking directly at the Sun with the naked eye or through any device or filter other than ISO 12312-2:2015 certified eclipse glasses may cause permanent damage and even blindness.

For the brief part of the eclipse known as “totality” (when the Moon completely blocks the Sun’s light), this is the only time when you can view the eclipse without any protection.

If you are using certified eclipse glasses or viewers and are in the path of totality, for the brief part of totality when you can no longer see any part of the Sun through your glasses, it is safe to take your glasses off. When any part of the Sun becomes visible after totality, you must put your glasses back on or look away. If you are not in the path of totality, even at 99.9% coverage, it is never safe to take your glasses off to observe the eclipse. If you are not sure if you will be in the path of totality or if you are not confident about knowing when and how it is safe to observe the eclipse, consider:

  • attending an official eclipse event on April 8th, 2024 led by qualified experts, where you will be informed when it is safe to look at the eclipse directly;
  • in the Hamilton-Burlington area the McMaster University Department of Physics and Astronomy has a group of eclipse ambassadors available to do presentations to your group prior to the date of the Total Solar Eclipse, complete the contact us form on this page to receive further information
  • attending a public eclipse lecture or planetarium show at McMaster University
  • arranging a graduate student guest speaker or portable planetarium show at your school, organization or business .

An alternative to eclipse glasses is projecting the Sun using a pinhole projector or box projector. You can make these on your own or order them online. Instructions on how to make these with your students can be provided with your McMaster University Department of Physics and Astronomy presentation or are available through the external resources links on this page.

A solar eclipse happens whenever the Moon passes between Earth and the Sun. A total solar eclipse happens when the Moon passes completely between Earth and the Sun.
This results in a narrow shadow zone being cast on Earth that’s known as the path of totality. In the path of totality, you’ll experience all five phases of a total solar eclipse from the first to final contact between the Sun and the Moon.
On April 8th, 2024, the path of totality will move west to east across Mexico, the United States and into Canada. If the weather cooperates, we’ll have a rare opportunity to see part of the Sun’s outer atmosphere (the corona and chromosphere). The bright face of the Sun, known as the photosphere, usually obscures its outer atmosphere.

The last total solar eclipse visible in Hamilton took place January 24, 1925.
After April 8th, 2024, the next total solar eclipse visible in Hamilton won’t happen until October 26, 2144.

The last total solar eclipse in Canada happened in February 1979, with the path of totality crossing through southern Saskatchewan and Manitoba, northwestern Ontario and far northern Quebec.  

After 2024, the next total solar eclipse in Canada won’t happen for another 20 years.

There are three important reasons why we should start planning now. 

The 2024 total solar eclipse will happen during the middle of the afternoon when most Hamiltonians are at work or coming home from school. It’s important than everyone is prepared and knows how to stay safe during the eclipse. Looking directly at the partial phases of a total solar eclipse without specialized protective eyewear can cause severe eye damage.   

We should also expect many visitors on April 8th since most of Ontario, including Toronto, will only experience a partial solar eclipse. Don’t be surprised if out-of-town family and friends ask if they can drop by for the day. There are also people who travel the world to experience total solar eclipses. 

And like an Arkells concert or a Ticats game, a total solar eclipse will be an ideal communal experience for Hamiltonians. Other communities that have experienced total solar eclipses bring people together for public celebrations.
