Warm weather is just around the corner, and that only means one thing: pool season is almost here.
Before diving into your pool on a hot summer day, you need to open your pool properly.
A smooth and safe opening helps you avoid costly repairs, keeps your pool equipment in top shape, and sets the stage for a stress-free season.
Get Your Pool Ready With Our Helpful Step-by-Step Guide
One of the best times to open your pool in Ontario is in late spring when the temperature is around 70℉ (around 21℃). We can’t wait for those temperatures to arrive, and we know you can’t either! Once they do, here’s what you can expect to do next:
1. Remove and Clean the Pool Cover
Start by clearing off any debris, water, or leaves that have collected on your pool cover. Use a pool cover pump or shop vac to remove standing water, and a soft broom or leaf blower to clear off leaves and twigs. Be careful not to let any of this debris fall into the pool when removing the cover. Once the surface is clear, carefully remove the cover, lay it out flat on a clean surface, rinse it with a hose, and allow it to dry completely (this prevents mildew buildup during storage).
2. Reinstall Pool Equipment and Accessories
During winterization, certain parts of your pool’s equipment were likely removed or covered for protection. Now’s the time to bring them back:
- Skimmer baskets
- Return jets and directional eyeballs
- Ladders, rails, and diving boards (tighten all bolts securely)
- Automatic pool cleaners or robotic units (if you use them)
Make sure all parts are clean, in good condition, and properly secured. Next, inspect all equipment before reconnecting them, such as the:
- Pump and filter system: Check for visible cracks, leaks, or signs of wear.
- Plumbing lines: Remove winterizing plugs and reconnect hoses or pipes. Be sure all fittings are tight.
- Heater (if applicable): Visually inspect it and confirm that all connections are secure.
Once everything is in place, prime the pump by filling it with water (if needed), then turn it on and check for proper operation. Look out for leaks or unusual noises and be prepared to shut it down if anything seems off.

3. Fill the Pool to the Right Level
After months of inactivity, your pool water level has likely dropped due to evaporation or intentional drainage during closing. Use a garden hose to refill the pool until the water reaches halfway up the skimmer opening. This ensures your pump has enough water to function correctly and helps with circulation once everything is running.
4. Give the Pool a Good Cleaning
Start by removing any visible debris from the water using a skimmer net. Then brush down the walls and floor of the pool to loosen dirt and algae that may have settled during the winter. Finally, vacuum the pool thoroughly, either manually or with a robotic cleaner. A thorough cleaning will make your water more manageable for balancing later and improve filtration efficiency.
5. Run the Filtration System
Once your pump and filter are running and your pool is clean, let the system run continuously for at least 24 hours. This helps to circulate the water and capture any remaining debris that may have been missed during manual cleaning. It also helps prepare the pool for the chemical treatment phase, which should be done after the water has had time to circulate.
6. Check for Leaks or Issues
With the system running, take time to walk around the pool and equipment pad and inspect for leaks. Check for:
- Drips or puddles near the pump, filter, or heater
- Air bubbles returning to the pool (a sign of suction-side air leaks)
- Any unusual sounds from the motor or filter
Catching issues early can save you both time and money, and give you peace of mind once you start swimming.
