Grab Bars & Wall Blocking
Grab bars fixed into solid backing, with the Building Code's 1.3 kN load rule and published per-bar prices.
About $200–$400 per bar installed (published Ontario and Canadian installer guides, 2025–26; yours will differ). Blocking in a closed wall costs extra.

A grab bar is only as strong as what holds it. Ontario's Building Code says that where grab bars are provided in a home, they must resist a load of at least 1.3 kN applied vertically or horizontally. Ask how each bar will be fixed: into studs or blocking, or into drywall alone.
For new houses, the Code (Article 9.5.2.4) requires reinforcement in the walls of the main bathroom so grab bars can be added later at the toilet, shower and tub. Whether a renovation of an existing bathroom must add that blocking is not something we found in the Code, so ask the City if your project includes a bathroom.
Grab bars are not on either of the City's permit lists.
Funding to check: the March of Dimes program lists grab bars, the Ontario Seniors Care at Home Tax Credit, a credit on eligible medical expenses for people 70 and over, names bathroom aids such as grab bars in its list, under its own rules, and the Home Accessibility Tax Credit covers renovations that reduce the risk of harm in the home. Each program decides eligibility.
Published guides put an installed grab bar at about $200 to $400 per bar. Adding blocking where the wall is already closed costs extra. Where to place a bar for one person's needs is a question for them and whoever advises them.
