    CRA Audits of Rental Income: What Triggers Them, and How to Stay Audit-Ready

    Real estate is the CRA's single biggest audit focus, and rental returns get looked at more than most. The good news: rental audits are predictable. They start from a short list of red flags — under-reported income, repeated losses, outsized repairs, mis-split mortgage interest, and over-claimed personal use — and almost always begin with a letter, not a knock at the door. This guide explains what actually triggers a review or audit, what survives one, and what to do if a CRA letter lands. General information, not tax advice.

    The Landlord's Year-End Tax Prep Checklist: Get Ready to File Your Rental Return

    Tax time is painful only when you leave everything to April. This year-end checklist turns filing your rental return into a four-step routine: gather your income and receipts, sort every cost into current vs capital, make the calls that matter (like whether to claim CCA), and file on time. It walks the documents to collect, the deadlines you can't miss, the two decisions that shape your tax bill, and the record-keeping that protects you in an audit — so the T776 becomes an export, not an ordeal. General information, not tax advice.

    The T776 Expense Deep-Dive: Every Rental Deduction Ontario Landlords Can Actually Claim

    The expense section is where a T776 is won or lost — it's the largest part of the form and where landlords both overpay (by missing deductions) and get audited (by claiming the wrong ones). This deep-dive walks every T776 expense line, the one distinction that governs all of them — current vs. capital — and the traps that trip people up: mortgage principal, your own labour, prepaid and prorated costs, and the personal-use split on a basement suite. Line by line, what you can claim and what you can't. General information, not tax advice.

    CCA for Ontario Landlords: How Rental Depreciation Works (and When Not to Claim It)

    Capital Cost Allowance lets Canadian landlords deduct a slice of their building's cost each year — but it's the most misunderstood line on a rental tax return. It's optional, it can't create a loss, and every dollar you claim can come back to bite you as fully taxed "recapture" when you sell. This guide explains how CCA actually works for an Ontario rental — the 4% Class 1 rate, the half-year rule, the land split, and the appliance classes — and, just as important, the situations where claiming it is a mistake. General information, not tax advice.

    Heat Bylaws in Toronto, Hamilton, and Ottawa: The Minimum Temperature Rules by City

    There's no single "Ontario heating law" — the minimum temperature your landlord must maintain, the dates it applies, and the fines all come from your city's bylaw. Toronto requires 21°C (Oct 1–May 15); Ottawa requires 20°C by day and 16.67°C overnight; Hamilton requires 20°C (Sept 15–May 15). This guide lays out the exact rules for all three cities, the provincial floor underneath them, the "calendar, not weather" trap that catches landlords every spring, how to complain when your unit is too cold, and the maximum-heat rules now emerging — for tenants and landlords alike.

    Pest Control in an Ontario Rental: Who's Responsible, and What to Document

    Bed bugs, cockroaches, mice — in Ontario, dealing with them is almost always the landlord's job, and paying for it is too. There's an actual regulation that says a rental must be kept "reasonably free of rodents, vermin and insects," a landlord can't pass the exterminator's bill to a tenant without proving the tenant caused the problem, and a "you deal with pests" lease clause is void. But tenants have real duties too — report fast, keep the unit reasonably clean, and cooperate with treatment. This guide draws the responsibility line, covers the cooperation trap on both sides, and shows exactly what to document — for tenants and landlords alike.

    Mold in an Ontario Rental: Who's Responsible, and How to Get It Fixed

    There's no "mold law" in Ontario — but there doesn't need to be. Mold caused by a building problem (a leak, bad ventilation, water getting in) is the landlord's to fix under the same duty to keep a unit in a good state of repair. This guide draws the responsibility line clearly: what the landlord must remediate (and pay for), the narrow cases where a tenant is on the hook, why "normal use" like showering and cooking is never the tenant's fault, and exactly how to document mold and enforce a repair with a T6 — for tenants and landlords alike.

    Maintenance Standards in Ontario: The Landlord's Duty to Repair (and How Tenants Enforce It)

    In Ontario, keeping a rental in good repair isn't optional or negotiable — it's a legal duty that a landlord can't sign away, and that applies even if the tenant knew about the problem before moving in. This is the complete guide to maintenance standards under the RTA: what "good state of repair and fit for habitation" actually means, the provincial and municipal standards that layer on top, who's responsible for what, and exactly how a tenant enforces it with a T6 — including what rent abatements real cases produce. For tenants and landlords alike.

    Vital Services in Ontario: Heat, Water, and What a Landlord Can Never Cut Off

    Heat, water, electricity, gas — these are "vital services" in Ontario, and a landlord can't withhold or deliberately interfere with them, ever. Not for unpaid rent, not for a damaged unit, not until an eviction is actually enforced. There's a minimum heat standard (and stricter city bylaws), a rule that makes the landlord responsible even when they forget to pay the utility bill, and clear remedies when a service gets cut off. Here's exactly what counts as a vital service, what a landlord must provide, and what to do when it fails — for tenants and landlords alike.

    The 24-Hour Notice of Entry Rule in Ontario: When a Landlord Can (and Can't) Come In

    Your landlord can't just show up. In Ontario, entering your rental almost always takes 24 hours' written notice, stating the reason and a time between 8 a.m. and 8 p.m. — and the LTB enforces that to the minute. But there are narrow exceptions (a real emergency, your consent at the door), a fixed list of valid reasons, and rules about what actually counts as "written" notice. Here's exactly how the entry rules work, and what to do when they're broken — for tenants and landlords alike.

    Tenant Insurance in Ontario: What a Landlord Can Actually Require

    Can your Ontario landlord make you get tenant insurance? There's no law that requires it — but a landlord can make it a condition of your lease, and once it's in a signed lease, it's enforceable. Here's what tenant insurance actually covers (your stuff and your liability, not the building), what a landlord can and can't demand, whether you can be evicted for not having it, and how to prove coverage — for tenants and landlords alike.

    Subletting vs Assignment in Ontario: The Difference That Changes Everything

    "Subletting" and "assigning" get used interchangeably — but in Ontario they're legally different, and mixing them up can cost you. A sublet means you're coming back; an assignment means you're gone for good. The rules on landlord consent differ too: a landlord can refuse a general assignment outright, but can't unreasonably refuse a sublet or a specific assignee. Here's exactly how both work — and the 30-day escape hatch most tenants don't know about.
