Absolutely not. I don’t live in Lytton, but close, and similarly hot. What is usually called a hot spell would be 34, 35, maybe 36 degrees. The last 3 days we’re well into the 40’s, approaching 50. I went out today and it was about 46 degrees. It hurt my eyes of all things. It’s brutally hot, and by the time I was done (I walked down to river to check temperature, maybe 20-30 minutes) I was spent. Not for this Canadian.

Well, we get hot summers, and cold winters, so houses should be well insulated (which serves both hot and cold) and air conditioners are common. So not completely unprepared, though it can be hard for A/C to keep up.

Edit: As I think of it, the Fraser Valley was fantastically hot, as was the rest of the lower mainland, which is usually mild weather (typical “pacific north west”) and I think less likely to have A/C installed. The Interior/Okanagan (Incl Lytton) are used to long hot summers, but not 50 degrees.
