Service began in 2018 with a single trial route, operating with a mixed fleet of low-floor midibuses and accessible paratransit vehicles.

It also connects to higher-order inter-regional transit services that operate within Central Ontario, including GO Transit (the Barrie GO train line and GO bus Route 68) and Ontario Northland's Sudbury-to-Toronto motor coach route through Barrie and Orillia.

The plan was based primarily around connecting pre-existing hub areas: Collingwood-Wasaga Beach, Penetanguishene-Midland, Barrie-Midhurst, and Orillia.

[3] These routes were remarked on as useful for commuters and intercity travellers entering or exiting the region, with new destinations such Napoleon Home Comfort (which employs over 700 people)[7] and the Allandale Waterfront GO Station, Barrie's primary intercity transit station which serves as the northern terminus for the GO Barrie line, as well as a stop for the Route 68 GO bus.

[7] Riders who use the reloadable LINX Card have an automatic 10% discount applied to their fare for adults, or 15% for students and seniors (65+).

[9] As of December 2024, LINX operates along the following routes:[2] The LINX fleet is composed of diesel buses from a variety of manufacturers, almost all of which were purchased through the Metrolinx Transit Procurement Initiative, through which Metrolinx, Ontario's provincial public transportation agency for the Golden Horseshoe region, coordinates procurement of transit vehicles for smaller rural and suburban transit agencies to reduce their procurement costs.

The fleet planned for the LINX soft service launch in August 2018 was four Grande West Vicinity midibuses, a Canadian-designed version of the fuel-efficient, mid-sized bus type often used for rural and suburban routes in Europe.

[3] In its second procurement stage in 2019, LINX received several Alexander Dennis Enviro200 midibuses, a model common in the United Kingdom.
