The number of COVID-19 cases — an umbrella term for ambulances — has spiked in Vancouver this year, to 64 in August, a sharp rise from the 20 a year ago. According to the Transportation Safety Board of Canada, of the 65 cases this year, there were 37 in the six weeks before August.

These are apparently not road accident calls. But they involve carbon monoxide detectors in buses that are off of service, making little to no traffic sense. And, of course, there are the rumors of the buses disappearing from the streets, to be filled by some sort of automated system.

Lynda Klein, an APS spokeswoman, says COVID-19s are safe for trains and people moving by bus, but buses need at least two firefighters to remove, and probably more.

The quick-moving weather in the north is killing the sun and the cold air will cause more carbon monoxide in the air as heating wanes and people carry on when they would normally shut off their COVs. Getting oxygen from inside an APS bus is difficult, if not impossible, in this scenario.
