Who handles what
The neighbourhood
The firm's office sits on Bay Street in downtown Toronto, the corridor that lends its name to the city's financial and legal establishment. Within the legal profession, the term Bay Street is often used as shorthand for Toronto's large, full service business law firms, though GMA is a smaller practice built around one specialty, condominium law, rather than a general Bay Street firm. Downtown Toronto has been through a sustained wave of new condo, office, and hotel construction since 2007, and that ongoing high rise growth keeps a condo focused firm busy in the core.
Frequently asked questions
- Does Gardiner Miller Arnold only handle condo law?
- No. Condominium law is the main focus, and all of the firm's lawyers are branded as CondoLawyers, but GMA also handles real estate transactions, business law, litigation and dispute resolution, and wills and estates.
- Can GMA represent a condo board in a dispute with an owner or a contractor?
- Yes. The firm's condominium practice covers turnover disputes and construction deficiency claims, contract negotiation, by-laws and rules, lien collection, mediation and arbitration, and running directors' meetings and annual general meetings.
- How much does it cost to incorporate a company through GMA?
- The firm's website lists a flat legal fee of $650 for a standard provincial (Ontario) incorporation, plus disbursements and tax. GMA also offers federal incorporation as a separate service.
- Will Gardiner Miller Arnold prepare a will and powers of attorney?
- Yes. The wills and estates practice covers wills and codicils, powers of attorney, living wills, and estate administration and probate, along with resolving disputes between beneficiaries.
- What happens on closing day when I buy a home or condo through GMA?
- According to the firm's real estate FAQ, keys change hands between lawyers on closing day rather than at the law office, and for a new build the builder may not release keys until later in the day, so GMA advises against booking same day movers.
- Where is Gardiner Miller Arnold located and how do I reach the firm?
- The office is at 390 Bay Street, Suite 1400, in downtown Toronto, and the firm can be reached at 416-363-2614.
