I flew yesterday on AC 115, YYZ to YVR. There were no temperature checks for me or for anyone else, as far as I could see (and I probably saw ~30 people board ahead of me).
I found this interesting since Air Canada's page on
temperature checks is actually quite definitive:
"Customers (including children) on Air Canada flights will be subject to an infrared temperature check. This non-contact procedure will be performed in the context of the existing government-mandated health questionnaire currently completed by travellers. Temperature checks are an additional layer of safety screening as fever is a common COVID-19 symptom.
