About AValois Law Professional Corporation

AValois Law Professional Corporation is a solo practice in Uptown Waterloo, run by Aida Valois, a barrister, solicitor, and notary public. The firm works out of the Marsland Centre at 20 Erb Street West, and it serves individuals and small to mid-size businesses across Kitchener-Waterloo and Guelph. Its main work is real estate, including buying, selling, and refinancing; wills, powers of attorney, and estate planning; estate administration and probate; and corporate and commercial matters for smaller enterprises.

Aida Valois practised law in Colombia for more than eight years before moving to Canada, and has worked in law for over 30 years in total. A law degree from Osgoode Hall Law School at York University followed, along with a call to the Bar of Ontario. That background carries into the firm's daily work: it offers services in Spanish and handles Colombian consular documents such as Fe de Vida life certificates, apostille authentication, and travel consent letters for children travelling abroad. AValois Law belongs to the Canadian and Ontario Bar Associations and the Waterloo Region and Wellington County law associations.

The neighbourhood

The office sits in the Marsland Centre at 20 Erb Street West, in the middle of Uptown Waterloo. Uptown is Waterloo's original commercial core, a compact district of banks, professional offices, and the shops along King Street. The Marsland Centre is an office building, home to tenants from the technology, financial services, and professional services sectors. For a firm whose work runs through real estate closings, small business deals, and estate files, that professional setting keeps it near the everyday commerce its clients deal in.
