Website maintenance in Canada usually costs about **CAD $50 to $400 a month** for a small business site. Larger or more complex sites cost more. The sources disagree somewhat, and several are agency blogs, so treat these as rough ranges.

**Typical monthly ranges**
- **Hobby or personal sites:** about $10 to $30.
- **Basic small-business upkeep:** about $50 to $200. This covers updates, backups, security monitoring and minor edits from a freelancer or small agency. One source's figures may be in USD, which would be roughly CAD $70 to $275.
- **Agency retainers (Toronto and Montreal 2026 pricing):**
  - $130 to $400 a month for a stable brochure-style site.
  - $500 to $900 a month for a site that is changing or has ongoing development work.
  - About $2,000 a month for a top tier with more hours and a fast response guarantee.
  - One Montreal source puts a marketing-site retainer at $1,300 to $5,200 a year.
- **Corporate, government or large sites:** $2,000 or more a month.

**Separate costs that often aren't in the plan**
- Shared hosting runs about $5 to $20 a month.
- Managed WordPress hosting runs about $25 to $60 a month.
- Domain renewal, SSL certificate, premium plugins and themes, and e-commerce or SEO tools cost extra.

**What affects the price**
- The platform, such as WordPress or e-commerce.
- How many content edits you want each month.
- How quickly the provider has to respond.
- Whether the site brings in leads or sales.

One source warns that a single emergency fix on a site with no maintenance plan can cost $1,200 to $3,800.
