Yes — significantly. A typical urgent care visit in Ontario costs $25–$75 with insurance (copay), or $100–$200 cash-pay for a basic visit. An ER visit averages $1,500–$2,500 even for non-emergency issues. Urgent care is appropriate for fevers, flu, UTIs, pink eye, minor injuries, strep, and most same-day concerns — reserve the ER for chest pain, stroke symptoms, severe bleeding, or trouble breathing.

All Ontario urgent care clinics accept walk-ins — that's their core business. Many large chains (MinuteClinic, AFC Urgent Care, Concentra, and Solv-partnered clinics) also let you reserve a time slot online to skip the waiting room. Wait times are typically posted live on each clinic's website.

Most adult urgent cares in Ontario see children age 1 and older. For infants under 12 months or complex pediatric presentations, look for dedicated pediatric urgent care — PM Pediatric Care, children's-hospital-affiliated walk-in centers, or pediatric-specific clinics. Check individual clinic pages for pediatric availability and age ranges.

Most Ontario urgent care clinics are open 8 AM to 8 PM, 7 days a week. Some major-chain locations (MinuteClinic, AFC Urgent Care, Concentra) offer extended or weekend hours, and a handful operate 24/7. Check the 'hours' line on each individual clinic page for current operating times — clinic schedules change, so we recommend confirming before travel.
