Planning a trip to East or Toronto and trying to figure out if I can even bring a blade of any type. So far google searches have just made it more confusing. Seems Canada has enacted some sort of crazy blades bans by way of court ruling, if I understand correctly, to give border agents more (read almost unending) discretion. I’m spoiled living in Free America and the South and would feel naked without some sort of blade but don’t want problems at the border. I’m sure when they see my VA medicine they’ll give me extra scrutiny. We will be driving and we all have our US passports. The wife became a US citizen years back from being solely a Canadian citizen. At least the Ham Radio reciprocity is much easier to deal with and easier to translate. Any solid advice would be appreciated!

I wouldn't bring a knife across the border. Make sure your scrips are in their original containers with labeling.

The CBSA also updated its list of prohibited weapons, which includes gravity, centrifugal, and automatic knives, among others. And Memorandum D19-13-2 outlines guidelines for the importing and exporting of weapons. Putting the two together provides a (somewhat) clearer understanding of what’s illegal to carry:

Automatic knife – Opens automatically by applying hand pressure to a button, spring, lever, or other device, in or attached to the handle of the knife, including knives that have a button, spring, lever, or other device located in the spine of the handle and attached to the inner part of the blade
Centrifugal knife (folding knife, butterfly knife, balisong knife) – Opens automatically through the use of centrifugal force, moving in a circular path and directed away from [the center of the body]; i.e., can be opened with a flick of the wrist
Gravity knife – Can be opened automatically by force of gravity even if the knife can be additionally controlled by a lever or button
Push dagger – The handle is placed perpendicular to the main cutting edge of the blade (or blades) and any other similar device
“Constant Companion” (Belt buckle knife) – A belt containing a blade capable of being withdrawn from the belt
Concealed blades under 30 cm – Any device having a length of less than 30 cm and resembling an innocuous object but designed to conceal a knife or blade; e.g., “knife combs,” penknives, lipstick knives, certain types of necklace knives, and knives contained in credit-card-sized cases clearly resembling real credit cards and designed as weapons
What Knives Are Legal in Canada?
Many forums are wrestling to define what folding knives are legal under Canadian Law. And much of it seems to be open to at least some interpretation. But CanuckSurvival.com sums it up well:

This law is about intent. This means if you’re caught with a knife that’s concealed on your person while in a location you don’t require a knife to be used as a tool, you may be in for a bad time.

While it’s not ironclad legal advice, generally speaking it’s not advised to carry any knife into situations where it’s not clearly needed. That said, the CBSA does outline some knives that are not prohibited:

Sword canes/umbrella daggers more than 30 cm in length – Swords contained in canes, frequently where the handle of the cane also serves as a handle for the sword sheathed inside the cane’s/umbrella’s shaft
Multitools/card tools – Credit-card-sized plastic cases that contain a number of small functional items such as scissors, a compass, and tweezers; these tools will almost always include a small blade or knife that is concealed by the plastic case; they are not designed as weapons but as functional tools
Certain thumb stud knives – Knives having “thumb studs” attached to the blade that are independent of the handle (not protruding from the handle in the closed or folded position), and that open automatically by applying pressure to the thumb studs
Note: Must not also act by gravity or centrifugal force; see above.
Clear as mud? It appears the law leaves a lot to the interpretation of law enforcement. Overall, it’s much more restrictive than other countries, namely the U.S. and even Australia. Carrying knives – even multitools – could be trouble. And it’s definitely not advisable to bring folding knives (or other weapons) into the country if there’s any question about its legality, especially if you don’t want to lose it at the border.

Use the criteria above to help understand the intent of the law. This article is not intended as legal advice, only to raise awareness of the issue. If you have any questions, call Canada’s Border Information Services or contact an attorney.

I would not bring a knife of any kind into Canada. What I do here in the US in the gun free so called safe zones, is carry a walking stick. No one has ever given me a second look with my walking stick as I am a grey beard that looks like I need help to get around. I don't but they don't know that. Also, my "walking stick" is a Japanese Jo, that is a fighting stick made of hickory. It looks just like any other walking stick, but can do a lot of damage to a bad guy if needed. Yes, I would rather have my gun but that isn't always possible.
