Closing Your Pool in the Fall| Important Pool Care Steps for Canadians

As the weather cools and the leaves begin to fall, it’s time to start thinking about closing your pool for the season. In Canada, where winters can be harsh, proper fall pool maintenance isn’t just about convenience. It’s about protecting your investment from costly damage.

Here are the most important steps for closing your pool this fall:

1. Balance the Water

Before shutting down for the season, make sure your water chemistry is balanced. Adjust pH, alkalinity, and calcium hardness to recommended levels. This prevents corrosion, staining, and scale buildup while your pool sits dormant.

2. Shock and Add Winterizing Chemicals

Shocking the pool helps kill off bacteria and algae that could grow under the cover. Follow up with a winterizing algaecide or enzyme treatment designed for long-term protection.

3. Clean Thoroughly

Vacuum the pool floor, brush the walls, and skim off any remaining debris. A clean pool at closing means an easier opening next spring. Don’t forget to empty skimmer baskets and remove any leaves that could stain the liner.

4. Lower the Water Level

For most pools in Ontario, you’ll want to lower the water level below the skimmer line to prevent freezing and cracking. Be sure to follow manufacturer guidelines for your pool type - concrete, vinyl, or fiberglass.

5. Drain and Protect Equipment

Disconnect and drain the pump, filter, heater, and chlorinator. Store them in a dry, covered space for winter. Blow out all plumbing lines to remove any standing water that could freeze and expand.

6. Cover It Right

A durable winter pool cover is essential. It keeps debris out and protects your pool from UV rays and harsh weather. Safety covers are especially recommended if you have children or pets.

7. Inspect for Repairs

Before covering, check for cracks, loose tiles, or worn coping. Scheduling repairs before spring ensures your pool is ready to go once temperatures rise.
