Fireworks FAQ

Whether you're lighting fireworks for the first or fiftieth time, there's always something new to learn. Here are answers to our customers' top questions. If you don't find what you're looking for, contact our fireworks experts by phone (1-888-502-5278) or email at sales@rocket.ca.

Do fireworks need to be buried or braced before lighting?

Yes—all aerial fireworks should be braced or buried before lighting to prevent tipping and dangerous sideways firing. Cakes and similar items can easily fall over if not secured, creating a serious safety risk.

Low-level Fountains and Ground Effects tend not to need bracing. .

Always check the instructions on each firework before setup. Canadian-approved fireworks include bilingual labels explaining proper use and ignition.

Can I light fireworks year round?

No—fireworks cannot be used year round in most areas. In Canada, rules vary by municipality, and many restrict use to holidays like Victoria Day and Canada Day.

Some areas allow use with a permit, while others prohibit fireworks entirely. Always check local by-laws or contact your municipality or fire department.

Where can I light fireworks? Can I use a park or schoolyard?

Fireworks can generally only be set off on private property with the owner’s permission. This includes homes, cottages, and approved event venues.

Public spaces like parks and schoolyards are typically not permitted unless explicitly allowed by local by-laws. Always verify before use.

Can I light fireworks at any time of day?

No—fireworks are typically restricted to certain hours. In many municipalities, you cannot light fireworks after 11:00 pm (sometimes 10:00 pm).

Check your local Fireworks or Noise By-law for exact times.

What is the shelf-life of fireworks?

Fireworks can last several years if stored properly in a cool, dry place. However, performance may decline over time if exposed to moisture or humidity.

Store fireworks in a cardboard box in a dry environment. Avoid sealed plastic containers, which can trap moisture and cause damage.

Can I light fireworks in damp or wet conditions?

Yes, but you must keep the fuse dry. Fireworks can be used in light rain or snow, but wet conditions can damage performance.

Place fireworks on a dry surface like plywood and avoid leaving them in wet ground for extended periods.

Can I buy coloured sparklers in Canada?

No—coloured sparklers are not permitted in Canada. All approved consumer sparklers produce gold sparks only.

However, you can achieve similar effects with alternatives like cake fountains or bottle sparklers, which are available in a variety of colours.

How are fireworks made and how do they work?

Fireworks work by igniting a lift charge that launches the shell into the air, where a timed fuse triggers an internal burst of effects. Inside each firework are components that control colour, sound, and pattern.
