Iron Ring Student Registration

Iron Ring banner

The Iron Ring may be worn on the little finger of the working hand by any engineer who has been obligated at an authorized ceremony of the Ritual of the Calling of the Engineer. The ring symbolizes the pride that engineers have in their profession, while simultaneously reminding them of their humility. The ring serves as a reminder to the engineer and others of the engineer’s obligation to live by a high standard of professional conduct.

You must attend The Ritual of the Calling of the Engineer Obligation Ceremony in order to receive an Iron Ring.

Frequently Asked Questions


Where and when do the Obligation Ceremonies take place?

The Ritual of the Calling of an Engineering takes place once a year. In 2017, the Obligation Ceremony for U of T Engineering undergraduates will take place on Saturday, March 4, 2017 at Convocation Hall. Your ceremony time will be indicated on your invitation card distributed by your undergraduate office. Please note: if you are late for your ceremony, you will not be admitted.

How to I sign up for the Obligation Ceremony?

Please click here to register to attend a ceremony. In order to participate, you must be eligible to graduate in spring 2017. Your name will be checked against the “Eligible to Graduate” list from the Registrar’s Office and you will be contacted if you are not eligible to participate.

Who can register for the Obligation Ceremony?

Graduating undergraduate students in the Faculty of Applied Science & Engineering. You must register online before February 17, 2017 to attend the ceremony.

What if I am a master's or PhD graduate?

Master’s and PhD students must first register with a provincial licencing body. You will need to demonstrate that you have met the academic requirements as an Engineering in Training (EIT) at the very minimum. Subsequently, you may apply to attend as a senior candidate, which takes place once a year in October. The application process is open from April 1 to June 30 and the application form is available only via the website at The registration number from your licensing body will be a requirement of the application. Additional information regarding this application process is available on the website. The cost for the application is $50 including HST.

I received my degree from another country. Can I apply to take the Obligation and get an Iron Ring?

The same process applies as above (master’s or PhD).

Can I get an Iron Ring in March if I am graduating in December?

No, unfortunately you will have to wait until next year’s ceremony.

Is it mandatory to attend an Obligation Ceremony?

No. It is a personal decision but you need to graduate and register in order to attend.

Do all engineers have to wear the ring?

No. The ring is unrelated to professional qualification.

Can I invite a guest to the Obligation Ceremony to present my ring to me?

Yes, but invited ring presenters must be obligated engineers (and wearing their Iron Ring on the day of the ceremony) and have at least four years of professional experience since graduation in order to be eligible to present a ring to another candidate.

Family members acting as invited ring presenters must meet the requirements noted above. Professors and other members of the University’s teaching staff cannot act as ring presenters to their own students (unless they are a relative of the student — i.e. parent, grandparent, spouse, etc.) and meet the requirement for invited Ring Presenters noted above.

The provisions noted here are required to ensure a mentor-candidate relationship between the Ring Presenter and candidate.

To invite a ring presenter, please complete the online application at before February 17, 2017. You will receive an email to confirm that your ring presenter can come to the ceremony by February 24, 2017.

Can I invite a guest to the Obligation Ceremony?

Yes, but invited guests must be obligated engineers (and wearing their Iron Ring on the day of the ceremony). Non-Obligated engineers are not allowed to attend the ceremony. Your invited guest will be seated on the second floor of Convocation Hall. They are not allowed to sit with you during the ceremony.

To invite a guest, please complete the online application at before February 17, 2017. Only one guest per attendee is permitted due to space limitations. You will receive an email to confirm that your guest can come to the ceremony by February 24, 2017.

What is the dress code?

The dress code for the Obligation Ceremony is business attire. Dress as though you are attending a job interview.

Can I get the ring without going to the Ceremony?

No. The Obligation Ceremony is about an engineer’s personal obligation to uphold the ideals of engineering. The Ceremony was designed such that engineers wishing to be obligated would do so “in the presence of my betters and my equals” (to quote from the Obligation). Candidates must take the obligation in the presence of senior engineers and fellow candidates. The Iron Ring serves as a reminder of the Obligation that you have taken. To give the ring without having participated in the Obligation Ceremony would nullify the meaning of the obligation.

Are there any guidelines for sizing my ring?

Yes, please take note of the following:

  • Your finger’s size will be affected by time of day, temperature, humidity, exercise and other factors. Your fingers tend to swell later in the day.
  • It is best to measure your ring size later in the day, at room temperature. Never measure when your hands are cold; allow them to warm to room temperature.
  • The ring must fit over the knuckle and sit comfortably at the base of the finger. The correct size will require you to twist once or twice to get it off the knuckle; otherwise, your ring will fall off when your hands are wet or cold.
  • If the ring slips easily over your knuckle when removing it, try a half size smaller.
  • If you are not used to wearing a ring, the proper size may feel a bit uncomfortable at first. Please allow two weeks before requesting an alternate size.

Can I change my ring size after I register?

No. You will need to know your ring size before registering online. Please get in touch with your Department Club Chair who will have a ring sizer or go to the Engineering Society office in Sandford Fleming. You can only exchange your size after the Iron Ring ceremony. You can’t change your ring size after you register.

Ring exchanges will be available on site at Convocation Hall immediately after each Obligation Ceremony. You can also exchange your ring at any time in the Camp One Office (GB 116).

What if I can’t attend the University of Toronto Obligation Ceremony?

If you are unable to attend the University of Toronto Obligation Ceremony on March 4, 2017, you can ask to be referred to another Obligation ceremony within Camp1 (York University, Ryerson University or University of Ontario Institute of Technology). Please contact the Camp One office at
