Hybrid motor regulations

Hi, I'm wondering if hybrid motors within the low to mid power range need to be certified? I live in Canada and I'm trying to build a mid power hybrid rocket.

Uncertified hybrid motors are experimental, which means ( in the US ) you'd need to be L2 at a TRA Research launch.

I don't know what that maps to up North. In any case, test burns on the stand ( again in the US ) have no particular restriction.

Hybrid motors are considered high powered, regardless of total impulse. So L2...

Here is a link to Transport Canada’s document on high power rocketry:
https://www.canadianrocketry.org/files/tc_hpr_reqs_jan00.pdf
9.1. All persons launching high power rockets in Canada shall use only commercially manufactured high power rocket motors, motor reloading kits or components authorized by NRCan and/or CLSO, except by deviation approval.

So, a person would need “deviation approval” to make a research motor, if I interpret that correctly.
Canada’s distinction between high power rocketry and high power rocketry is much less complex than here in the states. It’s possible that hybrids might be made that were model rocket motors, but I suspect a similar requirement for commercially available only applies.

My bad; I missed the important Canadian detail!

The "deviation approval" has me curious. Have you looked into what is required? What are your plans for the motor?
