As a Canadian myself, 17°C would be very cold for an indoor space. The standard recommendations (for offices at least) are much higher than that.
> Canadian Standards Association (CSA) and ASHRAE standards are used for thermal comfort and ventilation in indoor offices [....] These standards are a good resource to use when considering the thermal conditions in indoor office space.
> According to CSA standards Z1004-12 – Work place Ergonomics – the comfort level at work is determined by temperature, humidity, wind and work-rest cycle. The optimal temperature range for office comfort should be 23 to 26 °C with 50% relative humidity in summers and 20 to 23.5°C at 50% relative humidity in winter.
Gloves get worn at maybe -5C, -10C. Maybe.
