No push daggers, autos or auto-assist/spring-loaded or balisongs.
I'd tighten up the pivot a bit on any folders so it cannot easily be flicked open by Canada Border Services when crossing the border (you may not even be asked if you have any knives, however). If you are asked if you have any weapons - the answer should be "no" with respect to any knife you have. Your knife is a TOOL, not a weapon. If you are asked if you have any knives, answer honestly. Assuming they do not fall into the category of my first sentence, you are fine - but again - make sure your pivot is tightened so it cannot easily be flicked open. Once you are on this side of the border, re-adjust the pivot to your liking. Owning/carrying a "flickable" knife is not illegal in Canada, but they may not be imported or brought into Canada.
There are no length restrictions for folders or fixed.
NOTHING may be carried with the intent of SD or for use as a weapon.
Some establishments (and all federal and provincial government buildings) have a no weapons/knives policy - look for any posted signs before entering.
Don't draw attention to yourself and give me a reason to detain/search you, and you're golden.
Enjoy your stay!
