About Bykov Law

Bykov Law Professional Corporation is a small firm in North York, Ontario, run by founding partners Mayya Bykov and Oleksiy Bykov. Both hold a Juris Doctor from Osgoode Hall Law School and an undergraduate degree from York University. The firm's office is on Finch Avenue West, and it practices family law and criminal defence alongside real estate, business law, wills and estates, and notary and commissioner services.

Before opening the firm, Mayya Bykov worked as counsel to Ontario's Ministry of the Attorney General and Ministry of Finance, where the work included a General Anti-Avoidance Rule trial, matters tied to the 2014 Ontario provincial budget, and tobacco litigation, and included prosecuting regulatory offences in Provincial Offences Act courts. Oleksiy Bykov worked at the Crown Attorney's Office prosecuting criminal cases, including major crimes and homicides, and has since appeared in the Ontario Court of Justice, the Superior Court of Justice, and the Ontario Court of Appeal.

The firm serves clients in English, Russian, and Ukrainian, with separate Russian and Ukrainian language pages explaining its services for Toronto's Russian and Ukrainian speaking communities.
