Card-Based Certification in Ontario Construction: What Toronto Contractors Should Ask a Labour Lawyer

A union can win the right to represent a construction crew in Ontario without the workers ever casting a ballot in their favor. That surprises many contractors, who assume every certification ends in a vote. Under the construction rules, signed membership cards can be enough on their own. If you run crews anywhere in the GTA, a short list of questions for a labour lawyer Toronto contractors can reach quickly is worth having before any paperwork shows up.

Each question below matches a stage in the Ontario Labour Relations Board process. The answers come from the Board’s own published guidance for the construction industry. Bring these questions to your first call with any labour lawyer Toronto builders are weighing, and expect a clear answer to each one.

Question 1: How Does Card-Based Certification Differ from a Vote in Ontario Construction?

Start here, because the union picks the route, not you.

A construction union can apply under section 8, which is vote-based, or section 128.1, which is card-based. It cannot use both at the same time.

Under the card-based route, the membership count on the filing date shapes everything:

• More than 55 percent: The Board may certify the union without a vote, or it may direct a vote anyway.
• 40 to 55 percent: The Board must hold a representation vote, which usually starts five days after the Board directs it.

So a crew that looked lukewarm last month could be certified this month on paper alone. Ask your lawyer how the count works and who qualifies as an employee on that filing date. That second part is often less obvious than it sounds.

Question 2: What Happens in the First Two Days After a Union Files?

Here is how the clock works, and it moves fast.

The union must deliver a Construction Certification Package to the employer no later than two days after the filing date. Once you receive confirmation of filing, you must immediately post the application and the Notice to Employees where affected workers are likely to see them.

Your written response and your employee lists are due no later than two days after you receive the package. The Board counts only days it is open, so weekends and statutory holidays do not count.

Picture a drywall contractor with crews on three sites. If the package reaches the office on a Thursday afternoon, the response could be due the following Monday. Friday alone may not be enough to pull accurate lists together.

Useful things to ask at this stage:

• Who in your company receives legal documents, and does the site office know to send them right away?
• Do your employee lists match the bargaining unit the union has proposed?
• Where should notices go up so workers on every active site can see them?

Question 3: Can a Contractor See Which Workers Signed Union Cards?

The short answer is no. The union does not give the employer its list of members or the membership evidence. That evidence must be in writing, signed by each employee, and dated.

Wanting to know who signed is a normal reaction. Plenty of owners feel blindsided and want to understand what happened on their own crews. Still, asking workers about their union support, even casually, can open the door to an unfair labour practice complaint.

This is a good moment to ask your lawyer what supervisors can and cannot say. Perhaps put it in writing for your foremen, since they talk with crews every day.

Question 4: Is the Union’s Proposed Bargaining Unit Right for Your Company?

The union describes the group of workers it wants to represent. You do not have to accept that description.

Your response lists every employee in the union’s proposed unit. If you think a different unit fits better, you also list the employees in your version. Where several job sites are involved, each employee’s name is tagged with a site code.

Ask your lawyer some pointed questions here:

• Does the description match the trade work your people actually do?
• Are the right job sites included, or did the union reach too broadly?
• Could a different unit change the membership percentage?

That last question matters because the 55 percent line depends on who sits inside the unit. A small change in the description could shift the math, though not always in your favour.

Preparing Your Toronto Construction Company Before an Application Arrives

Most of the risk in card-based certification sits in the first few days. After that, the decisions on the bargaining unit, voter lists and disputes follow the Board’s process.

Before an application ever reaches your office, read the Ontario Labour Relations Board’s Information Bulletin No. 6 on construction certification. Then arrange a conversation with a lawyer experienced in construction labour relations. Keep your employee records current too, because that part of the response is hard to fix in two days.

Whether an organizing campaign is coming to your sites is harder to predict. Being ready for one is much easier.
