What a union certification application means
A union certification application is a formal request to the Ontario Labour Relations Board (OLRB) to represent your employees.
If successful:
- the union becomes the exclusive bargaining agent
- you must negotiate terms through collective bargaining
- individual employment relationships fundamentally change
This is a permanent shift, not a temporary issue.
As Christopher Achkar, employment lawyer and founder of Achkar Law, explains:
“Union certification applications move quickly and leave little room for error, making early decisions critical for employers. Understanding your obligations and responding appropriately from the outset is essential, which is why speaking with an experienced employment lawyer immediately can help protect your business and avoid costly missteps.”
How certification happens (what employers need to know)
- A union must show at least 40% support
- If successful, a vote may be held
- If over 50% vote in favour → certification granted
However:
In some cases, certification can happen without a vote
This often occurs if:
- the employer interferes with union activity
- unfair labour practices are found
This is where employers get into serious trouble.
What employers cannot do (high risk area)
During a union campaign, employers must not:
- threaten job loss or discipline
- promise raises or incentives to discourage unionization
- interfere with employee decision-making
- target employees involved in organizing
Even informal comments can be used as evidence.
Violations can result in automatic certification without a vote
What employers can do (but carefully)
Employers can:
- communicate factual information
- respond to employee questions
- continue normal business operations
But everything must be:
- neutral
- accurate
- non-coercive
This is where legal guidance is critical.
Employer response window (this is critical)
Once notified of an application:
Employers typically have 2 business days to respond
This includes:
- identifying the proposed bargaining unit
- raising objections or concerns
- preparing evidence
Missing this window can severely limit your ability to respond.

Factors that can impact certification
Employers may challenge:
- the composition of the bargaining unit
- inclusion of certain employees (e.g. management roles)
- whether proper support thresholds are met
However:
These challenges must be raised quickly and properly
Special risk: unfair labour practice findings
If the OLRB finds employer interference:
- certification may be granted automatically
- penalties or remedial orders may apply
- your ability to influence the process is lost
This is one of the biggest risks employers face.
What this means for your business
Union certification affects:
- wages and compensation structures
- scheduling and operational flexibility
- discipline and termination processes
- long-term labour costs
This is not just legal, it is operational.
Best practices for employers
- seek legal advice immediately
- train managers on communication limits
- centralize all responses to union activity
- document interactions carefully
- avoid reactive or emotional decisions
The goal is compliance + strategic response
Final takeaway
A union certification application is one of the most significant legal events an employer can face.
Mistakes made early are difficult, or impossible, to undo.
Employers who respond properly can:
- protect their legal position
- avoid unnecessary findings
- manage the process strategically
