Commercial Real Estate Investing in Canada: A Beginner's Guide (2026)

Commercial real estate covers apartment buildings of 5 or more units, retail, industrial, office, mixed-use and specialty property. This page covers the property types, the metrics used to value them, a worked apartment-building example, lease structures, the ways to invest and the risks. It is part of WealthNorth’s guide to investment property financing; apartment buildings and CMHC’s multi-unit financing are covered in more depth in multi-family investing, and commercial loans in commercial mortgages.

Types of commercial real estate

Property type	Description	Typical lease	Complexity
Multi-unit residential (5+ units)	Apartment buildings	Residential tenancies under provincial law	Moderate
Retail	Plazas, standalone retail, malls	Multi-year, often net	Moderate to high
Industrial	Warehouses, distribution centres, flex space	Multi-year, often net	Moderate
Office	Office buildings, professional centres	Multi-year, gross or net	High
Mixed-use	Retail ground floor with residential above	Both kinds	Moderate
Self-storage	Storage unit facilities	Month to month	Low to moderate
Hotels	Hotels, motels	None: nightly operating business	Very high

Cap rates differ by type, location and tenant quality, and move with interest rates; cap rate explained covers how to read them.

Key metrics

Metric	Formula	What It Tells You
Cap rate	NOI ÷ purchase price	Return on the asset (unlevered)
Cash-on-cash return	Annual cash flow ÷ total cash invested	Return on your actual capital invested
NOI	Gross income − operating expenses	Property earnings before debt
DSCR	NOI ÷ annual debt service	Can the property cover its mortgage?
GRM	Purchase price ÷ gross annual rent	Quick comparison tool (lower = better value)
Price per unit	Purchase price ÷ number of units	Per-unit cost comparison
Price per sq ft	Purchase price ÷ total rentable sq ft	Cost comparison for office/retail/industrial
Occupancy rate	Rented units ÷ total units	How full is the building?
Break-even occupancy	(Operating expenses + debt service) ÷ gross income	What occupancy level is needed to cover all costs?

Investment analysis example

A 12-unit apartment building (illustrative assumptions)

Item	Amount
Purchase price	$2,000,000
Down payment (25%)	$500,000
Mortgage ($1,500,000 at an example 5.5%, 25-year amortization)	$9,156/month
Gross annual rent ($1,500 × 12 units × 12 months)	$216,000
Vacancy (5%)	−$10,800
Operating expenses (40% of gross)	−$86,400
Net operating income (NOI)	$118,800
Annual mortgage payments	$109,870
Debt service coverage (NOI ÷ payments)	1.08
Annual cash flow	$8,930
Cash-on-cash return	1.8%
Cap rate	5.94%

The building covers its mortgage with little to spare: a debt service coverage ratio barely above 1 leaves almost no margin and may not meet a lender’s minimum, so it could need more down payment, higher rents or lower costs to be financed. The same calculations for any property are in the rental property calculator.

Lease structures

Lease Type	Who Pays Expenses	Common In	Investor Impact
Gross lease	Landlord pays all expenses	Office	Higher rent but more expense risk
Modified gross	Shared: base year expenses by landlord, increases by tenant	Office	Moderate risk sharing
Single net (N)	Tenant pays property tax	Varies	One less expense for landlord
Double net (NN)	Tenant pays tax + insurance	Varies	Two fewer expenses
Triple net (NNN)	Tenant pays tax + insurance + maintenance	Retail, industrial	Minimal landlord expenses: most predictable income
Absolute net	Tenant pays everything, including structural	Single-tenant retail	True passive income for landlord

Ways to invest

Method	Capital needed	Control	Liquidity	Complexity
Direct ownership	Large down payment plus reserves	Full	Low	High
Syndication or limited partnership	Set by each offering; some are for accredited investors only	None	Very low	Low for the investor
Public REITs	One unit	None	High	Low
Private REITs	Set by each offering	None	Low to moderate	Low
Mortgage investment corporations	Set by each offering	None	Low to moderate	Low
Joint venture	Varies	Shared	Low	Moderate

For direct ownership of an apartment building, CMHC’s standard multi-unit insurance lends up to 85% of value, and MLI Select up to 95% on an existing building that meets its affordability, energy-efficiency or accessibility commitments; uninsured commercial loans usually need more equity.

Publicly traded REITs by sector are covered in REITs in Canada, and individual picks in the best Canadian REITs. REITs are regularly acquired or taken private, so confirm a trust still trades before buying. Private options are compared in investing in real estate without buying property.

Due diligence checklist

Financial

Reviewed 3 years of income and expense statements
Verified rent roll against actual leases
Confirmed current occupancy and lease expiry schedule
Calculated NOI, cap rate, DSCR, and cash-on-cash return
Reviewed property tax assessments and appeals history
Identified upcoming capital expenditure needs (roof, HVAC, elevator, parking lot)
Assessed below-market rents (upside potential) or above-market rents (risk)

Physical

Commissioned a building condition report
Ordered a Phase I Environmental Site Assessment (ESA)
Reviewed recent and planned capital improvements
Assessed deferred maintenance
Confirmed zoning permits current use
Reviewed building code compliance

Legal

Reviewed all leases: terms, renewal options, tenant rights
Confirmed no outstanding litigation
Reviewed title: easements, encumbrances, liens
Confirmed property tax status (no arrears)
Reviewed insurance claims history

Risks

Risk	Details	Mitigation
Vacancy	Losing a major tenant can eliminate cash flow	Diversify tenants; maintain a lease expiry schedule
Interest rate	Higher rates reduce cash flow and property values	Fixed-rate mortgages; stress-test at higher rates
Market decline	Economic downturns reduce demand and rents	Buy in strong locations; diversify property types
Liquidity	Commercial properties take months to sell	Maintain cash reserves; do not overleverage
Capital expenditure	Roofs, mechanical systems, elevators and parking structures are expensive to replace	Building condition report; reserve fund
Environmental	Contamination liability can be severe	Phase I ESA before purchase; environmental insurance
Tenant default	Commercial tenants can go bankrupt	Creditworthy tenants; lease guarantees; diversification
Regulatory	Zoning changes, rent control (residential), building code upgrades	Due diligence; legal review

Getting started: a path for beginners

Stage	Action
1. Education	Read, take courses, network with investors, attend real estate meetups
2. REITs	Start with public REITs for exposure and education: low capital, liquid
3. Small multi-residential	Buy a 2–4 unit building (residential rules, lower capital) to learn landlording
4. Small commercial	Move to a 5–12 unit apartment or small retail/industrial property
5. Scale	Add properties, consider syndications, build a portfolio
6. Diversify	Spread across property types and geographies

Tax points for commercial property

Item	Details
Interest and operating costs	Deductible against the rental income
Depreciation	Capital cost allowance on buildings is optional, and CCA claimed can be recaptured as income if the building sells for more than its undepreciated capital cost
Holding and refinancing	Refinancing instead of selling defers the capital gain, since borrowed money isn’t income
Corporations	Rental income in a corporation is usually passive investment income, not eligible for the small business rate unless the business has more than 5 full-time employees; see real estate investing in a corporation
GST/HST	Commercial rent is generally taxable, so a registered landlord charges GST/HST and claims input tax credits; long-term residential rent is exempt, so an apartment building’s owner generally can’t
