Gurmej Singh Gill appeared today at an Immigration and Refugee Board hearing in Vancouver.
The Canada Border Services Agency alleges Gill was at one time the head of Babbar Khalsa, an organization that has or will engage in terrorism.
Gill came to British Columbia, where he once lived, in November and was reportedly planning on returning to his home in Birmingham, England, when border officials ordered him to appear before the immigration board under the security section of the Immigration Act.
Gill was arrested once before, more than a decade ago, upon his arrival at the airport in Vancouver and he was sent back to England.
Babbar Khalsa is a Sikh separatist group linked to the 1985 Air India bombings that killed 331 people on two flights that originated in Vancouver.
