The San Jose, Calif.-based company cited "economic conditions" as the reason for the labour reduction in an email.
Michael Kovacs, Sanmina's senior director of marketing and public relations, said the company remains committed to the Kanata facility, and to the industries it supports in Ottawa.
He declined to provide any additional information.
The company is also losing its top Kanata official.
Cyril McKelvie, who was executive vice-president for optical microelectronics at Sanmina and former president of BreconRidge, said that he was no longer working for the company when contacted by OBJ. He did not discuss the circumstances behind his departure.
The layoffs mark a significant shift from the tone Mr. McKelvie struck earlier this year in an interview with OBJ marking the one-year anniversary of the acquisition. At the time, Mr. McKelvie called the Ottawa facility the "centre of gravity" for the optical microelectronics division. He said that BreconRidge employees gained security in the acquisition by being a part of a global company.
Sanmina said in 2009 it was purchasing BreconRidge for its expertise in its advanced broadband technologies, and its wireless, radar, and satellite applications.
Sanmina-SCI had over 500 employees before the layoffs, according to Ottawa Technology Magazine.
