I have not specifically asked them about admitting homeschooled students, but they do allow teachers to register (teachers get in free) and bring groups of students or students may attend on their own.  I see no reason why they would choose to exclude homeschoolers, but you never know.  Please contact the university at the phone number below to confirm.

From their brochure (pdf):

Interaction provides a unique opportunity for university bound secondary school students in grades 10 and 11 to experience the university living and learning community at Guelph. Session topics cover a wide range of issues and subjects and will be presented by faculty, staff and students from a variety of academic disciplines and student services areas.

Students choose one morning session and one afternoon session from dozens of choices including subject-specific themed sessions such as

• Science in Sports: How Sports Fields Are Maintained and How They Impact the Urban Environment
• Wild in the Rainforest
• Microscopy of Food – What the Eye Cannot See!
• Let Your Colours Burst: “Designimation”

as well as university-orientation themed sessions such as

• Tips for Financial Planning
• Setting Yourself Apart: Opportunities and New Horizons
• Your Orientation Starts Now: Finding Your Voice, Your Place, Your Way
• The Co-operative Education Advantage

You must register for this conference by Monday, April 11, 2011. Registration is $30 and includes lunch. If you require special assistance, please call 519.824.4120, ext. 58713.  An application and brochure can be found at http://admission.uoguelph.ca/interaction

While collecting information on Open Universities (Athabasca University and Thomspon Rivers University) for the upcoming KW Christian Home Educators’ conference, I discovered that the University of Guelph now has an Open Learning Program with “no formal admission requirements.” Their website goes on to say:

Guaranteed Admission to a B.A. Program

English proficiency requirements as outlined in the Undergraduate Calendar apply. Contact Admissions at 519 821-2130 for details.

Open Learning program students with no previous post secondary experience who complete four courses (2.0 credits) with a 70% minimum cumulative average, may qualify to transfer into the Bachelor of Arts or Bachelor of Commerce Programs at the University of Guelph. Please contact the Office of Open Learning for information regarding these opportunities, since there are different course requirements for each program. Please note: University of Guelph admissions requirements are subject to change at anytime

Way to go, Guelph!
