How it started

History

In 2012 the company started planning and digging for fibre delivery to Windsor with a gradual roll-out of upgrades through to 2020. It will be an expected investment of more than $35 million. The service is available in Walkerville, Oldcastle and East Windsor.

The company is using its own fibre lines and the bandwidth is not purchased from a larger company. MNSi uses a local call centre.

In 2017, MNSi became a sister company with Central Ontario communications company Nexicom. In November, 2016, Nexicom received The Outstanding Business Achievement Award by The Kawartha Chamber of Commerce and Tourism.
