Colby, the Counter Assault bear spray you linked to says for bears
& should perform equally to the others I’ve carried such as UDAP & FRONTIERSMAN. I prefer to purchase here in the US, due to the 2% active ingredients compared to Canada’s 1%, but as Bob says they may confiscate it though in my opinion it is a very slim chance they will deny the 2% when crossing the border. I’ve crossed many times since 2001 with the 2% with no problem & only asked a few times if I had bear spray & then when answering yes, asked only if it it said for bear use on it. I have never even been asked to show it. On two different times when we were carrying several containers of bear spray all the US 2%, the border agents did extensive vehicle searches, followed by never even mentioning the bear spray, they had to have found.
In the Army, when I went through the gas testing, I dropped my helmet in the process of getting the mask on & that automatically brought on having to stay in the chamber longer without the mask. I’ll never forget having to sing the Yellow Rose of Texas, while trying to shake off the effects of the gas, but I did it with little effect other than burning watery eyes & throat. I’ve also been hit with the bear spray & it’s many many times worse than tear gas. I found it almost impossible to breath & I felt like I was on fire all over. It would have been impossible for me to sing.
Bears, like people have different personalities, along with changing attitudes, that can come with having cubs, guarding food sources, territory, bad encounter with other bears, being surprised, sick, hungry or just feeling ill tempered at the time. This can make how one should react in an encounter only good for generalities with the more bear knowledge gained from others & personal experience with them, determining a somewhat better chance of future interactions turning out positive for the person & bear. For sure, worst case is a surprised bear, very close, especially if it’s with a cub or guarding a food source. Bear spray will most likely not stop an enraged bear, but such encounters are very rare, so for most people it’s the best option for bear defense. I’ve used pistol flares, pencil & 12 gauge bangers & shooting slugs close by them with varying good results to being totally ignored. One thing that’s also worked has been being aggressive back at them, but I’ve only done this with shotgun in hand & in a area where they weren’t surprised or close to start. On other encounters where I could, I’ve chose to back off when bears were edging closer, following my using flares or bangers. Bears are to be respected, but not overly feared. In my observation of bears, especially those that are not habituated to humans, their first reaction to an encounter 90% or more of the time is to run immediately or stand up & try to see if you may be a threat & then run away. I see this same effect in their encounter with other bears, when it’s a surprise meeting.
I love observing bears in their territory & have spent considerable time doing it.
