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.

The neighbourhood

Bigdeli Law's office is in North York City Centre, the cluster of highrise towers along Yonge Street. The building sits near the south end of that district, close to the Sheppard-Yonge subway interchange, where Line 1 and Line 4 meet and which ranks among the busiest stations in the TTC system.

A good share of the firm's immigration and refugee work involves clients who are elsewhere in Canada or applicants still overseas, so the North York office isn't the only way the firm meets with people. Immigration files typically start with a free 15-minute introductory session, whether that happens in the Sheppard Avenue office or online, and the firm notes that for civil litigation matters this first session isn't a legal consultation itself.

Frequently asked questions

My IRCC application was refused. Can Bigdeli Law challenge the decision?
Yes. The firm's judicial review practice takes refused visa, study permit, and other IRCC decisions to Federal Court when the refusal looks unfair or based on an error, and a related mandamus application is used when a file has simply stalled beyond normal processing times.
Does Bigdeli Law handle spousal sponsorship or study and work permit applications?
General immigration work at the firm covers study permits, visitor visas, spousal sponsorship, permanent residence through Express Entry, and work permits, with a free 15-minute introductory session offered before a file is opened.
I'm fleeing danger in my home country. Does Bigdeli Law handle refugee claims?
Yes. The firm represents refugee claimants at hearings before the Refugee Protection Division.
I'm an entrepreneur or investor who wants to move my business to Canada. Can Bigdeli Law help?
Business immigration work at the firm covers programs including the Start-Up Visa, C11 significant benefit applications, intra-company transfers, and provincial nominee programs for entrepreneurs and investors.
Does Bigdeli Law take on civil disputes outside immigration, like a contract or property dispute?
Yes. Through a network of affiliate lawyers, the firm represents individuals and businesses in Ontario's civil courts and tribunals on contract disputes, debt collection, property disputes, and defamation claims.
Is service available in a language other than English?
Yes, the firm's website and intake are also offered in Farsi.
