So sorry about the family bereavement.

First, a really silly question. It appears that your flight will be strictly in Canada, so, do domestic Canadian flights observe USA TSA rules?

If TSA applies, here is a site the TSA has with lists for various items: https://www.tsa.gov/travel/security-screening/prohibited-items. I took a quick look at your video, and the only things I noted was the stove---anything flammable might be a problem, e.g. the esbit tabs, and leatherman and SAK. Remember, liquids, including creams and gels and pastes have their own limits. Another helpful site: https://www.tsa.gov/travel/security-screening/liquids-rule

Also, airlines have their own restrictions, so check with them, in particular size/weight for carry on and checked bags. These do vary with airline and type of aircraft and ticket class.
