About David Hager

David Hager runs an independent employment law practice from an office in First Canadian Place on King Street West in downtown Toronto. Hager was called to the Bar of Ontario in 1976, after a B.A. in Honours Economics (1971) and a J.D. (1974), both from the University of Toronto. From 1981 to 2013, Hager was a partner at Lang Michener LLP and its successor firm, McMillan LLP, and chaired the firm's Employment and Labour Law Group from 1999 to 2008.

Since then, the practice has focused on wrongful and constructive dismissal, severance packages, employment contracts, and shareholder disputes, including oppression remedy claims under Ontario's and Canada's business corporations legislation. Hager has presented employment law papers for the Law Society of Upper Canada, the Ontario Bar Association, The Board of Trade, Federated Press, and Lorman Education Services, and received Martindale-Hubbell's BV Distinguished peer review rating every year from 1999 to 2021 for ethical standards and professional ability. The practice serves clients across the GTA and southern Ontario.

The neighbourhood

The office is in First Canadian Place, on King Street West at the corner of Bay, in Toronto's Financial District. Completed in 1975, the 72 storey tower has ranked among Canada's tallest office buildings for decades and holds a mix of law firms, banks, and other professional tenants above a retail concourse. It's a downtown Toronto address built around phone and online consultations rather than walk in visits, which fits a solo litigation practice that draws clients from across the GTA and southern Ontario rather than a single neighbourhood.

Frequently asked questions

I was let go from my job without any notice. Can David Hager help?
Yes. The practice concentrates on wrongful dismissal, including cases where an employer denies proper notice or pay in lieu of notice, and can advise on the value of a notice period or severance package.
My employer changed my duties and pay without asking me. Is that constructive dismissal?
It can be. The firm explains constructive dismissal as a substantial change to a fundamental term of employment, such as pay, duties, or reporting structure, made without the employee's consent, and notes that employees need to respond promptly rather than let the change sit unchallenged.
I'm a shareholder in a company and was also fired as an employee. Can David Hager help?
This is one of the practice's specific service areas. The firm advises shareholders, including minority shareholders, on oppression remedy claims under Ontario's and Canada's business corporations legislation, and on the added complexity that arises when a shareholder is also an employee who has been terminated.
Should I file an Employment Standards Act complaint or pursue a claim in court?
The firm's site cautions that filing a complaint under the Employment Standards Act can prevent a later common law claim for higher damages, so it's worth getting advice on which route to take before filing anything.
How long has David Hager been practising law?
Hager was called to the Bar of Ontario in 1976 and spent more than three decades, from 1981 to 2013, as a partner at Lang Michener LLP and its successor firm, McMillan LLP, before establishing an independent practice.
Where is the office and how do I book a consultation?
The office is in First Canadian Place, 100 King Street West, Suite 5700, in downtown Toronto. Consultations are arranged by phone at 416-915-4126 or through a confidential enquiry form on the firm's contact page.
