Understanding Rent Control in Ontario

Rent control is one of the most discussed topics in Ontario’s rental market. Many tenants assume that all rental units are subject to annual rent increase limits, while many landlords are unsure about when those rules apply.

In reality, Ontario has a rent control exemption that applies to certain properties, which significantly changes how rent increases are regulated.

What Is Rent Control?

In Ontario, rent control refers to the government guideline that limits how much a landlord can increase rent each year for most residential units.

For example, the province sets an annual percentage increase (such as 2–3%), and landlords of rent-controlled units must follow this limit unless special approval is granted.

Which Units Are Exempt From Rent Control?

A key rule that is often misunderstood is this:

👉 Rental units first occupied after November 15, 2018, are generally exempt from rent control.

This includes:

• Newly built condos
• Basement units created after that date
• New additions or substantially renovated spaces that became new residential units

For these properties, landlords are not bound by the annual rent increase guideline.

What Does “Exempt” Actually Mean?

For rent control–exempt units:

• There is no fixed percentage cap on rent increases
• Landlords can raise rent based on market conditions
• However, proper notice (typically 90 days) is still required

It is important to note that exemption from rent control does not remove all regulations. Landlords must still follow Ontario’s Residential Tenancies Act (RTA) rules.

How Does the 2.1% Rent Increase Guideline Fit In?

While some rental units in Ontario are exempt from rent control, many properties are still subject to the province’s annual rent increase guideline.

For 2026, the Ontario government has set the rent increase guideline at 2.1% for rent-controlled units.

This means that for eligible properties:

• Rent increases are capped at 2.1% annually
• Landlords must follow the guideline unless approved for an above-guideline increase
• Proper notice requirements still apply

However, it is important to distinguish between rent-controlled units and exempt units.

• If a unit is subject to rent control, the 2.1% cap applies
• If a unit is exempt (first occupied after November 15, 2018), the cap does not apply

Because of this distinction, many landlords and tenants often misunderstand which rules apply to their specific situation.

Common Misunderstandings

1. “All rental units in Ontario are rent-controlled”

This is not correct. The post-2018 exemption means a significant portion of newer units are not subject to rent caps.

2. “Landlords can increase rent anytime”

Even for exempt units, rent increases:

• Can typically only happen once every 12 months
• Require proper written notice

3. “Older buildings and newer condos follow the same rules”

They do not. The difference in first occupancy date can completely change how rent increases are handled.

Why This Rule Exists

The rent control exemption was introduced to encourage new housing development.

By allowing flexibility in rent pricing for newer units, policymakers aimed to:

• Increase housing supply
• Encourage investment in rental properties
• Support new construction projects

However, it also creates a more complex rental landscape where different properties follow different rules.

What This Means for Landlords

For landlords, understanding whether a unit is rent-controlled or exempt is critical.

For exempt units:

• Rent can be adjusted to reflect market changes
• Pricing strategy becomes more important
• Clear communication with tenants is essential

For rent-controlled units:

• Increases are limited
• Long-term planning becomes more important

What This Means for Tenants

For tenants, the key takeaway is to understand the type of unit before signing a lease.

Important considerations include:

• Whether the unit is subject to rent control
• Potential future rent increases
• Lease terms and notice requirements

Being aware of these factors can help avoid unexpected changes later.

Conclusion

Ontario’s rent control exemption is one of the most commonly misunderstood aspects of the rental market.

While many units are still subject to annual rent increase limits, properties first occupied after November 15, 2018, are generally exempt, allowing for greater flexibility in rent adjustments.

For both landlords and tenants, understanding these rules is essential to making informed decisions and avoiding confusion in the future.
