There are a HUGE number of hikes in the area around Vancouver from easy to hard
A couple of the more popular ones are
The Grouse Grind
Lynn Canyon
Lots of info on them if you google it
Downtown Vancouver would have people going bug eyed if you had a fixed blade strapped to your side
On a hiking trail no one would look twice
You get a lot of yuppie hippie dippy types on the Grouse Grind so a smaller fixed blade would be the order of the day
If you are further out away from the city day trails, no one much cares what you are packing
You can also google the Trans Canada Trail
Or if you are staying down town the Stanley Park Seawall is nice
In Canada
Push knives
Automatic knives
Gravity knives
Balisongs
Knuckle knives
Knives with blades under 12 inches long that are disguised as something else I.e belt buckles, hair brush or pens
Are all prohibited
Also NEVER carry a knife for self protection in Canada, that makes it a prohibited weapon
It is always to be used as a tool
I have carried knives my whole life and never had an issue
Pm me if you need more information
