How to Store Ammunition Safely in Canadian Weather

Introduction

If you’re a Canadian hunter or sport shooter, you already know that weather can make or break your gear—and ammunition is no exception. From freezing winters in Alberta to humid summers in Ontario, improper storage can ruin your investment in quality ammo. Worse, it can compromise safety and reliability when you need it most. Storing ammunition safely in Canada isn’t complicated, but it does require attention to detail.

In this guide, we’ll cover everything you need to know about storing ammunition safely in Canadian weather, ensuring long-lasting performance and peace of mind.

Understanding Ammunition Sensitivity

Ammunition isn’t invincible. It can degrade over time if exposed to the wrong conditions.

• Temperature: Extreme heat can weaken gunpowder, while cold can cause moisture buildup.
• Humidity: Moisture leads to corrosion of casings and primers, making ammo unreliable.

In short: ammo likes the same environment you do—dry, moderate, and stable.

Canadian Weather Challenges for Ammo Storage

• Cold Winters: Sub-zero temperatures can cause condensation when ammo is moved indoors.
• Hot Summers: High heat can affect ammo stored in garages or sheds.
• Humidity: Especially in coastal regions, moisture buildup is a constant threat.

General Principles of Safe Ammo Storage

The golden rule: Keep it cool, dry, and consistent.

• Avoid direct sunlight.
• Keep ammo away from furnaces, heaters, or damp basements.
• Store in sealed containers to protect against air and moisture.

Best Storage Locations in Canadian Homes

• Basements: Good if dry, but risky if prone to flooding.
• Garages: Avoid unless insulated and climate-controlled.
• Indoors: Locked cabinets or safes inside your home are ideal.

Using Ammo Cans for Storage

Military-style ammo cans are a hunter’s best friend.

• Steel Construction: Protects against impact.
• Rubber Seals: Keep out moisture and dust.
• Stackable Design: Saves space in hunting cabins.

Moisture Control Tips

• Place silica gel packs or desiccants inside ammo cans.
• Use vacuum-sealed bags for long-term storage.
• In winter, let ammo warm up gradually indoors to prevent condensation.

Temperature Management

• Winter: Avoid leaving ammo in vehicles overnight. Rapid shifts from -20°C to room temperature create condensation.
• Summer: Don’t store ammo in direct sunlight or in uninsulated sheds where temperatures can exceed 35°C.

Transporting Ammo in Canadian Weather

When traveling to hunting trips:

• Store ammo in a separate locked case from firearms (required by law).
• Keep it out of direct sunlight in vehicles.
• Avoid leaving it in trucks overnight in freezing conditions.

Ammo Longevity: How Long Does It Last in Canada?

• Rifle and Pistol Ammo: Can last 10+ years if stored properly.
• Shotgun Shells: Often degrade faster in humid conditions.

Signs of bad ammo: Corroded casings, discolored primers, or failure to fire.

Safety Regulations in Canada

Canadian law requires safe storage of ammunition.

• Must be stored separately from firearms.
• Must be kept in a locked container if more than 225 kg in possession.
• Firearms Safety Courses recommend climate-controlled storage.

Best Commercial Ammo Storage Products in Canada

• Cabela’s Canada: Lockable ammo boxes and gun safes.
• Canadian Tire: Affordable storage cases and ammo cans.
• Pelican Cases: Waterproof and shockproof options for serious hunters.

Common Storage Mistakes Hunters Make

• Leaving ammo in glove compartments or trunks year-round.
• Storing firearms and ammo together in unlocked cabinets.
• Ignoring humidity control in cabins or cottages.

Tips for Seasonal Hunters in Canada

• Rotate your ammo stock before each hunting season.
• Use older rounds at the range and save new ones for the hunt.
• Keep extra ammo sealed after each trip.

Summary

Storing ammunition safely in Canada isn’t complicated, but it does require attention to detail. Between freezing winters, humid summers, and damp cabins, Canadian weather poses unique challenges. By using airtight ammo cans, controlling moisture, and following federal regulations, you’ll keep your ammo reliable, safe, and ready for your next hunt. Storing ammunition safely in Canada isn’t complicated, but it does require attention to detail.
