Diploma in Interior Decorating is a diploma in Interior Design programme offered by Sheridan College in Oakville, Canada. The programme runs for 2 years, delivered on campus. Teaching is in English. Tuition for international students is CAD 19,858 per year (CAD 4,901 per year for local students).
Training takes place in a studio setting using industry-standard software such as CAD, SketchUp, 20/20 and Photoshop, with a focus on 2D and 3D rendering, plus access to finishes, paints and samples in a dedicated resource room and occasional visits to design and product showrooms. A three-week work placement is included.
Students learn to plan and decorate residential and small commercial spaces from initial programming through to final presentation drawings, draft to professional standards to communicate design concepts, use freehand drawing and mixed media in presentations, and design and implement marketing and sales strategies. Coursework is supplemented by guest lectures from suppliers, decorators and designers, and covers the Ontario Building Code; students use their own laptop and have ongoing access to lecture notes, assignments and course resources.
Requirements
Admission Requirements: Direct entry requires an Ontario Secondary School Diploma or equivalent including English, Grade 12 at the ENG4C or ENG4U level. Applicants aged 19 or older who lack this prerequisite may apply as mature students; they may be required to complete assessment testing in English, math and/or science, or a preparatory course through Sheridan's Academic Upgrading program. Selection ranks the average of an applicant's six highest senior-level credits, including the required course; no portfolio submission is stated for admission. Sheridan's institution-wide English proficiency requirement for certificate and diploma programs applies to applicants whose first language is not English: IELTS Academic 6.0 overall with no band below 5.5, TOEFL iBT 80 with no section below 20 (a redesigned iBT scale applies from 2026), PTE Academic 58 with no section below 49, Duolingo English Test 105 with no subscore below 85, or CAEL 60 with no section below 50.
Application Details
Start Date:Sheridan runs three terms a year - Fall starting in September, Winter in January and Spring/Summer in May. For 2026-27 the Fall term ran 8 September to 18 December 2026, Winter runs 6 January to 16 April 2027, and Spring/Summer runs 3 May to 13 August 2027. On 6 September 2026 this program's own page listed September 2026 and January 2027 intakes at the Hazel McCallion Campus in Mississauga, plus online-synchronous intakes open to domestic applicants. Sheridan's Start date table also carries a separate Domestic and International status for each intake (Available, Waitlisted or Closed) that changes as seats fill, so check this program's page on sheridancollege.ca before you apply.
Application Deadline:Sheridan publishes no deadline of its own for this program; the dates below are the college-wide ones. DOMESTIC APPLICANTS (Canadian citizens and permanent residents) apply through ontariocolleges.ca, which opened the Fall 2027 application on 26 September 2026 - Sheridan says it starts receiving those applications in early October for the academic year that follows. The equal consideration date is 1 February: apply on or before it and your file is weighed alongside every other one received by then for a Fall-term start, so for the cycle now open that means 1 February 2027 for entry in September 2027. Sheridan still accepts applications after that date wherever a program has not filled, but they are handled in the order they arrive, which leaves little room in high-demand programs. First offers for a September start may go out from 1 November; programs that require a portfolio, audition or resume begin issuing decisions later in March, and offers for the Winter and Spring/Summer intakes are made on a rolling basis. Confirm a Fall offer at ontariocolleges.ca by 1 May, or by the date printed on an offer issued after that, then pay the tuition deposit three months before the term begins. INTERNATIONAL APPLICANTS apply instead through Sheridan's own International Application Portal, and Sheridan publishes no deadline for them - its Important Dates table carries only a note that the international dates are still to be posted. What limits an international application in practice is space: Sheridan tells international applicants to check that a program still has room before applying, and every program page shows a separate International status for each intake. Apply as early as you can and leave time for a study permit. Confirm the current dates at sheridancollege.ca and ontariocolleges.ca before you apply.
