About Bigdeli Law Professional Corporation

Bigdeli Law Professional Corporation, which also operates online as BigdelX, is a Toronto immigration, trade, and civil litigation firm with an office in North York. The practice is led by Dr. Sadeq Bigdeli, a barrister, solicitor, and notary public in Ontario who also teaches immigration law as an adjunct professor at Osgoode Hall Law School, York University. Work at the firm centers on immigration and refugee matters, including judicial review and mandamus applications, general and complex immigration files, business immigration for entrepreneurs and investors, and refugee protection claims, along with civil litigation handled through a network of affiliate lawyers.

Bigdeli's academic background runs alongside the law practice. Bigdeli holds a PhD and a master's degree from the University of Bern in Switzerland, and a Master of Laws from Harvard Law School, where administrative law and judicial review were studied under Professor Cass Sunstein. Before establishing the Toronto practice, Bigdeli was a full time law professor in New Zealand, as a senior lecturer at the University of Waikato, and later at Shahid Beheshti University's law school in Iran, and completed a postdoctoral fellowship at Georgetown Law School. The firm's website is available in English and Farsi.
