Freezing temperatures outside are not the main issue. The bigger factor is what happens when cold air enters your home and gets heated. Cold air holds less water vapour than warm air, so once it is warmed up without any added moisture, the relative humidity drops.

Wood trades moisture with the air around it. When the air is dry, wood releases moisture and shrinks, mostly across the grain. When humidity rises again, it takes moisture back in and swells. This is seasonal wood movement. It is normal for solid hardwood like maple, oak and walnut, and it does not mean a piece is defective.

It can, mostly when the wood is stressed by big moisture swings or when its movement is held back. A tabletop is made from several boards. If it is fastened down rigidly, the boards cannot shrink freely, and that stress can show up as a split or a stressed joint.

This is why joinery matters. A well-made top is attached in a way that lets the wood move, and it is built from properly dried material. A small, temporary change at a seam is not the same as a structural crack. If a gap keeps growing, a joint lifts or a new split appears, take a photo and contact your maker before trying a DIY fix.

A room that looks finished is not always ready for solid wood. Fresh paint, plaster and other materials can add moisture while they dry, and then the room swings drier once the heating settles into its winter routine. Before delivery, make sure wet materials have dried, the permanent heating is running normally and the floors are done.

Moving day matters too. A piece coming off a cold truck into a warm house needs care. Arrange delivery into a clean, heated space, keep it away from snow and slush, and ask your maker when to remove protective wrapping. Avoid leaving finished hardwood in an unheated garage for long stretches. Plan delivery around the real condition of the room, not just the calendar.

Where you put the table matters. A vent blowing warm air across one end creates uneven drying. Keep wood away from fireplaces, radiators and strong direct sun, and keep vents unobstructed. If you are renovating a dining room, check vent, window and fireplace locations before settling on the layout.

A small hygrometer is an inexpensive way to see what your home is actually doing. Canadian residential guidance commonly puts a useful indoor range at about 30% to 50% relative humidity, with lower settings sometimes needed in the coldest weather to avoid window condensation. Oil does not replace humidity control. A finish slows moisture exchange but cannot stop it, so follow the care instructions for your specific finish.

You do not need to be a woodworker to buy well. Species matters, but movement also depends on grain direction and how the piece is made. The best table for an Edmonton winter is a well-built one, not simply the darkest or priciest wood. Good questions get honest answers.
