Three Toronto-area residents have been charged in an immigration fraud case by Canada Border Services Agency (CBSA).

The agency says the trio were arrested at a Mississauga residence last week by officers with a search warrant following an 11-month investigation.

They were charged with several offences under the Immigration and Refugee Protection Act.

Investigators allege Eliza Lazaro and Cecilia Bautista, also known as Cecilia Agtarap, acted as unauthorized immigration consultants, and provided false information to clients and government officials in order to obtain Canadian visas.

They also allege Lazaro's husband, Bernabe Lazaro, assisted by providing false information in order to obtain visas.

CBSA alleges Eliza Lazaro has been operating as an unlicensed immigration consultant since 2009.

Investigators say she tells prospective clients that for a fee, she will find them employment in Canada and take care of the Labour Market Opinion paperwork which is necessary for them to obtain a Canadian visa and work permit.

A total of 37 charges were laid in the case, including misrepresentation and human trafficking.

All three accused appeared in Brampton court last Wednesday.
