Microsystems International Limited (MIL) was a telecommunications microelectronics company based in Ottawa, Ontario, Canada, founded in 1969.

[1][2] MIL was an early attempt to create a merchant semiconductor house by Nortel Networks (then Northern Electric).

Electronic manufacturers were at that time forced to create custom integrated circuits due to the lack of industry standard ICs.

Northern Electric entered the field partly at the urging of the Canadian federal government even though it had strong doubts of the viability of the company.

[6] The MIL fabrication facility continued to operate as the largest semiconductor fab in Canada until Nortel's bankruptcy in 2009.
