What is ACORN?

ACORN stands for Accessible Campus Online Resource Network. For students, ACORN will replace the existing ROSI Student Web Service (SWS). For those unfamiliar with the existing system, it’s where students enrol in courses, check fees and finances and do other records and registration tasks such as making updates to address and contact information.The purpose of ACORN is to provide a more convenient, personalized and guided experience for students using U of T’s online services.

What changes and improvements can I expect in ACORN?
  1. A more modern look and feel
  2. An enhanced dashboard
  3. Fully redesigned and enhanced course and program enrolment screens
    1. New – Enrolment cart: Prior to your enrolment open window, proactively save course activities to your cart and easily enrol in them later
    2. Enhanced – Course and program search: Search by code or keyword with autocomplete results displaying after four characters
    3. Proactive warnings displayed for:
      1. Pre and co-requisites (if your division uses Degree Explorer)
      2. Courses you blocked from enrolling in
      3. Course load limits for terms/session (Undergraduate: UTM, UTSC, St. George Arts and Sciences, Architecture)
      4. Credit/no-credit totals (if your division uses credit/no-credit)
  4. New ‘Life’ section: Highlighting important student services and programs on each campus. We’ll highlight services such as:
    1. Housing, getting involved (Co-Curricular Record, clubs etc), international opportunities, jobs and career planning, health and wellness and accessibility.
  5. Integrating information and providing easy connections to other complimentary online services and systems such as Degree Explorer, Blackboard Portal, Co-Curricular Record and the Career Learning Network.
  6. UTORid will replace student number and PIN for logging in
  7. Personalized notifications for upcoming important deadlines, prompts for to take action (pay fees), and confirmations of actions occurring outside of the ACORN system (payment processed, grades posted).
What’s the most useful thing that’s been added to ACORN?

It really depends on your needs and goals as a student. Based on student feedback to date in our usability and beta tests, most students have found the new enrolment cart and enhanced autocomplete course search to be the most useful features in ACORN.

Your enrolment cart is used to plan ahead of time the courses and activity sections you intend to enrol in later. Feel free to add to your cart different back-up course section combinations, or add entirely different courses in case they become necessary.

Note: Courses in your enrolment cart will not automatically be enrolled in once your enrolment period begins.

Learn more about how to Add courses to your enrolment cart.

Are there any features in ROSI that won’t be in ACORN?

No, we haven’t removed any features in ACORN that are currently in ROSI. We have either redesigned existing ROSI functionality or added new functionality where it makes sense.

I am a new student at U of T, do I have to learn about ROSI?

You may have seen specific references to ROSI in materials that your Registrar or academic unit contact has provided. While you may use ROSI for the first few months here at U of T, we will be transitioning solely to ACORN in the near future. In the meantime, you are free to use either system.

Does ACORN have scheduled downtime like ROSI did?

Yes, but significantly less than in ROSI previously. Scheduled downtime will be weekly on Monday mornings from 3:00 am – 6:00 am EST.

How was the name ACORN chosen?

The Office of Vice-Provost, Students ran a contest in early 2012 called “Name the New ROSI”. The winning entry submitted by a student in the Doctor of Dental Surgery (DDS) program was announced on April 18th, 2012. The name was selected because of its simplicity and the acronym ties to U of T’s logo oak imagery. The adjudication panel for the Name the New ROSI Contest met in early April and reviewed the nearly 1000 entries for the contest. Submissions were received from undergraduate and graduate students representing a range of programs from across the University’s three campuses.

Should I use ACORN or ROSI? What are the differences?


Signing in Sign in using your UTORid and password, which is integrated with several other U of T services like Portal and UTmail+. Sign in using a PIN that is only used on ROSI.
Course search You can search for a course by course code or title. You have to know the specific course code and section to search for a course.
Enrolment day You can save all your desired course activities in an enrolment cart prior to your enrolment day and enrol in each course with the click of a button. You must type in the course and section code for each course you want to enrol in, then manually type in the codes for any additional activities for those courses. 
Timeout You are timed out of ACORN after 20 minutes of inactivity. You are timed out of ROSI after 5 minutes of inactivity.
Course and activity information On a single page, ACORN shows instructor names activity times and locations for your courses. ROSI only shows your course names and times.
Legacy ACORN will replace ROSI within the next few months as your new student web service. If you are an upper-year student, you may already be familiar with ROSI and prefer to not adopt a different system before completing your degree.


Are there any opportunities to contribute to the programming or design side of ACORN?

We often hold usability tests in our User Experience Design lab at 215 Huron street. During these 30-45 minute tests, we invite U of T students to come in and test new designs and features that are in the works. It’s an opportunity for you to see what the ACORN team is currently working on, learn about our UX design process, and it also gives us a chance to meet you and find out how we can improve ACORN to make your student life easier. If you participate in 5 sessions, you’ll also get a credit on your Co-Curricular Record (CCR)!

You can sign up to take part by filling out this form. We do hire work-study students from time to time, and when positions are available you can find them on the Career Learning Network (CLN).

What will happen if I enrol in courses that result in a timetable conflict?

ACORN will not take any additional actions if you enrol in courses that result in a conflict (i.e it will not drop any course activities on your behalf). It is up to you to resolve any conflicts. You can either leave the courses as they are or enrol in alternative options. 

You can try to resolve the conflict in a few different ways:

  • Explore different combinations and permutations of course sections
  • See if you can take one of the courses at a later term
  • Select a different course if one of the conflicting courses is not required to complete your program or degree
Which browsers are supported by ACORN?

What is ACORN’s Peak Load Mode?

ACORN dashboard with peak load mode enabled
ACORN’s Peak Load Mode is a simplified version of ACORN that is enabled on peak enrolment days to reduce load on the system and improve performance. An example of a peak enrolment day is when priority course enrolment controls are removed for Arts and Science courses on August 4th for the 2017-2018 academic year. The ACORN team will announce these dates ahead of time.

Note: When peak load mode is active, please do not refresh your browser while your course enrolment actions (e.g. enrol, switch section, drop) are in progress, or take the same enrolment actions in multiple browser tabs. ACORN will currently be under peak load, so enrolment actions will take longer than usual to complete, but are in progress even if the system is slow to respond. Refreshing your browser or repeatedly requesting the same action will only slow the system down further and increase the likelihood of your request being rejected entirely.

Why are some of ACORN’s services temporarily disabled?

Due to the high volume of traffic during key enrolment days, the ACORN team has temporarily disabled some ACORN features not essential to course and program enrolment to reduce the load on the system and its supporting infrastructure.

What features and information are disabled or unavailable during peak load periods?

Disabled locations within ACORN

  • Notifications
  • Your invoice
  • Financial awards and aid information
  • Multiple degree invitations, if applicable

Note: All functionality required for course and program enrolment is available.

When will full functionality be restored?

ACORN’s “Peak Load Mode” will only be enabled on isolated high-traffic dates. Regular functionality will be restored within 24 hours.

Please email us at rosi.help@utoronto.ca if you have any questions or comments.

Launch and Transition Period

When was ACORN launched?

June 22, 2015.

What happens to ROSI now that ACORN has launched?

We are planning to have both ACORN and ROSI available to use in parallel until ROSI is retired. This means that for those students graduating you won’t need to learn a new system and for other students this gives you a chance to get used to ACORN before we make the full transition.

Will changes I make in ACORN show up on ROSI?

Yes. We won’t be changing the underlying database, so any changes made to one system will show up on the other.

If I don’t want to use ACORN, can I continue using ROSI?

Yes, for a period of time both ROSI and ACORN will be available at the same time for a transition period. ROSI will be available until Spring 2016, at least through the end of the winter term. This will allow students to explore ACORN and switch over slowly if desired.

How long will ROSI remain available?

To be determined, as of May 2016, we are aiming for late 2016 though this is dependent on providing the ability for certain student populations to activate their UTORid from off-campus. This issue delayed our initial intent to retire ROSI-SWS in Spring 2016.

Where can I find out more about ACORN?

If you are still curious to learn more about ACORN and haven’t found what you are looking for here or on the Introducing ACORN site, feel free to contact us with your questions or comments.

Can I use ACORN and ROSI at the same time?

Yes, you could if you really wanted to. Both systems will use the same underlying database meaning any change made to one system will be reflected on the other.

Financial Planning Calculator FAQs

What is the Financial Planning Calculator?

The Financial Planning Calculator is an online tool that will help you estimate what it will cost to attend the University of Toronto for one academic year. It will be coming to ACORN in the future, but at the moment it is a standalone publicly-available tool.

Who can use it? Anybody who wants to learn more about costs associated with attending U of T. This includes current U of T undergraduate, graduate and second-entry students, prospective students (high school and potential transfer students), parents, staff or guidance counsellors.

This is purely an exploratory planning tool for you to use; any information you enter will not be associated with you or your financial status at the University.

Learn how to use the Financial Planning Calculator.

Where do the expenses in the Financial Planning Calculator come from?

The Financial Planning Calculator is meant to provide a quick way to approximate what the upcoming academic year will cost, so many of the expenses used are educated estimates or averaged values. Costs for off-campus housing, groceries, entertainment and personal care are based on typical costs of living and eating healthy in Toronto, while tuition, on-campus housing, transportation and meal plan costs are calculated by drawing from more precise data provided by the University and current public transit prices.

Awards & Aid FAQs

How will I know if I’ve received an award?

If you have received an award in full, it will appear in the Received awards area of the My Awards screen.

If you have received at least one payment for an award and currently meet the criteria to receive future payments for that award, the payment schedule will be displayed in the Upcoming awards section. Please note that future award payments may be affected if your registration status changes and you no longer meet the award’s eligibility criteria.

Why Does My Award Payment Have a Cancelled Status?

If one or more payments of an award that will be paid to you or has already been paid to you is cancelled, it will appear with a Payment Status of “Cancelled” in the Upcoming or Received section. The award’s issuing department will contact you with details about why it was cancelled and how you should proceed.

Can I Save or Print my Awards History?

Yes. If you have a record of any awards on the My Awards page, simply click “Print Awards History” and you will be prompted to save or print a PDF version of the page.

Confirmation of Enrolment Letter FAQs

What is a Confirmation of Enrolment letter?

A Confirmation of Enrolment letter is an official document that can be used to verify your status as a student at U of T. If you are a Faculty of Arts & Science student, you can download a Confirmation of Enrolment letter in PDF format via ACORN by visiting the Transcripts & Enrolment Confirmation page. If you are not a Faculty of Arts & Science student, please contact your registrar to get a Confirmation of Enrolment letter.

Learn how to generate a Confirmation of Enrolment letter.

What do I do if the Confirmation of Enrolment letter I generated in ACORN doesn’t contain all the information I need?

Since the letter is automatically generated using your registration information within ACORN, there are limitations with the information we are able to include. If you need a letter that is more customized than what ACORN offers, please request one from your registrar.

What do I do if I want my Confirmation of Enrolment letter to include a different graduation date, or if it doesn’t give me the option to include it at all?

ACORN does its best to predict when you might be graduating, plus or minus one year. It can only do this accurately if you are a full-time student. If ACORN does not have all the information it needs to make an accurate prediction for any other reason, you will unfortunately not be able to include your graduation date in the letter. Please request one from your registrar in this case.

UTORid and Password Reset

How do I log in to ACORN?

Similar to other U of T systems like Blackboard Portal or Degree Explorer, you will use your UTORid and password to log in to ACORN.

Will I still need my ROSI login PIN?

If you choose to continue using ROSI during the transition period to ACORN, you will still be required to use Student Number & PIN to login. ACORN will be using UTORid.

Why is ACORN using UTORid for login instead of ROSI’s PIN?
  • PIN is much more susceptible to compromise
  • UTORid has better security monitoring and responses in the event of a compromised account
  • UTORid has an existing infrastructure allowing self-serve password resets for students
  • UTORid credentials are easier for students to remember due to frequent use
  • UTORid allows for secure single sign-on and other convenience features

Future Releases

Will the invoice or other financial screens be improved?

Eventually yes, but not in the initial release. The finances module on ACORN is slated for redesign in the second phase of work which is already underway. We tackled as much as we could with the first phase of ACORN and are looking forward to rolling out additional enhancements ongoing.

Is ACORN optimized for mobile? Will there be an app?

In its first release, ACORN was optimized only for a tablet and desktop setup. We have since released an optimized responsive version of ACORN for smartphones that can be accessed without downloading an app.

Can I contribute to future ACORN project work?

We have been fortunate to have over 1000 students involved in ACORN to date through interviews, surveys, usabilty tests of early stage prototypes and beta tests of our test site. If you would like to participate in future activities, please complete and submit our sign-up form. We’ll email you for opportunities to get involved as they arrive, typically once per month, give or take.

Is there an official U of T tool that can help me map out my timetable?

Yes! An official Timetable Builder is currently available for UTSC students. In the future we will be branching out to include additional faculties, so stay tuned for more information.
