I can't be certain, but it appears that Jonathan may be wearing some sort of medical monitoring device, similar to a Holter monitor. The name for the device that is clipped on the fingertip is an Oximeter. It monitors your oxygen saturation level and also would give your heart rate. While the device(s) he is wearing give the appearance of valid devices, it also could be just Jonathan's own home made look-at-me-I'm-a-special-sick-snowflake type of gear.
The thing around his neck that looks like a car fob is a Telus GO. Which is his ISP. If they do yank his fiber-optic Internet access over his making death threats, he'll be filing to BCHRT that he's "discriminated" against as a disabled person.
