For an accounting practice in Ontario, you have four main options. I didn't find a single "best" provider, so this is a guide to who to call and what to ask.

**Who to call**
1. **A web design agency that works with accounting or professional-services firms.** Parachute Design in Toronto says it has built accounting firm sites across Canada for almost 20 years. Look for portfolio examples, a clear price, and who owns the site and domain when the work is done.
2. **A local Kitchener-Waterloo freelancer or small agency.** This is good if you want to meet in person. Ask to see other professional-services sites they've built.
3. **A DIY builder (Squarespace, Wix, WordPress) with a freelancer for setup.** This is the cheapest route and works well for a small practice.
4. **An accounting-specific website provider.** Some vendors sell templates built for accountants. These can be quick, but you may be locked into their platform.

**What the site should include**
- Clear descriptions of your services.
- Team profiles and credentials.
- Client testimonials.
- A way to contact you.
- A trust-building, professional look.

**Compliance**
- Your professional body regulates how you advertise. Ads can't be false, misleading or unsubstantiated.
- You can't list services, such as audit, that nobody at your firm is licensed to provide.
- Designations must be shown correctly in the firm name and staff bios.
- The rules I found were from CPA British Columbia, not CPA Ontario. Check CPA Ontario's advertising and firm-name rules, or call them, before you publish.

**Before you hire anyone**
- Get 2–3 quotes.
- Ask who owns the domain and the content.
- Ask about ongoing hosting and maintenance costs.
- Ask whether they know the professional advertising rules.
- Ask for references from other professional practices.
