Unican Security Systems Ltd. was a Canada-based company created by Aaron Fish in the 1960s and sold in 2000.
Fish then promptly moved from being a distributor to being a developer, and created the first push button lock in North America.
Over the next 4 years Unican acquired 5 companies, from die casting Capitol Industries to key-maker Ilco in Fitchburg, Massachusetts.
In November 2007, Fish bought back the original east-end Montreal plant where the company began.
The Montreal Gazette on Sept. 6, 2008 reported that the company now specializes in zinc die-casting and finishing, mainly for metal furniture parts such as door handles.
