Quick answer: A tenant generally cannot block entry that is lawful, properly noticed and reasonably necessary for pest inspection or treatment. Landlords are responsible for maintenance and pest response, but must comply with entry rules and consider legitimate health, disability, pregnancy, pet and preparation concerns.
Sections 26 and 27 of the RTA govern entry. Non-emergency pest work usually requires at least 24 hours’ written notice stating the reason, date and a reasonably specific time between 8 a.m. and 8 p.m.
The landlord should use a qualified provider, supply preparation and safety information, and comply with pesticide and public-health requirements.
Can the tenant demand a different treatment?
A tenant may raise medical or safety concerns and request accommodation, but cannot necessarily choose the treatment. The landlord should consider effective alternatives and professional advice.
Who must prepare the unit?
Reasonable preparation steps may be required from the tenant. The landlord should provide clear instructions and consider disability-related assistance where needed.
What if access is repeatedly refused?
The landlord should document notices and attempts, communicate consequences and use the appropriate LTB process rather than forcing entry outside the law.
What should the tenant do?
- Report pests promptly and follow reasonable preparation instructions.
- Raise medical, disability, pregnancy or pet-safety concerns early in writing.
- Keep the notice and treatment materials.
- Offer reasonable alternative access rather than simply refusing.
What should the landlord do?
- Give proper written notice and reasonably specific timing.
- Use qualified pest-control providers and share preparation and re-entry instructions.
- Coordinate treatment across affected units where necessary.
- Document access problems and use lawful remedies.
Example
A landlord gives proper notice for a licensed technician to treat bed bugs and provides safety instructions. The tenant generally cannot cancel without a valid reason, but a documented respiratory disability may require accommodation planning.
