I agree with all that S Bengi says above, and in addition, if you're line drying clothing indoors, of course that adds moisture.
Combustion of gas produces steam as part of its exhaust, so if you use a gas stove without running an exhaust fan, that can add a lot of moisture to the air (as well as, if it's making noticeable moisture you may even be increasing the carbon monoxide in your house!) If adding a ventilator fan seems too difficult, replace some of the cooking with electric versions like an electric kettle, microwave, or the electric pressure cooker below.
A pressure cooker does some great things: it keeps most of the cooking moisture from boiling out into the house, it cooks things much faster, and it uses much less energy to cook the same thing. Pressure cookers are commonly used all over India so I'm used to it, but maybe it sounds too exotic for Canada, I don't know. The Instant Pot is a big hit in the US the past couple of years, an electric pressure cooker with lots of timer settings that make things easy. It can do things like soak your beans and then pressure cook them after the soaking time is finished, or slow-cook stews. It releases less steam into the house than doing the same on the stovetop in a normal pot.
