Hi - Is there code requirements in Ontario that posts can not be horizontal (to 'allow' climbing)?
Yes code requirement is that vertical rails be used and that they be no greater than 4 inches apart and that if a bottom rail is used it must be on the outside of the rail so that balusters cannot be kicked or knocked off from the stair side.
If you are referring to horizontal balusters than as long as your baluster openings are to be less than 100mm than you will not have an issue with climbing.
OBC A-18.104.22.168.(3) - according to the ontario building code they do not recommend horizontal balusters especially if you have young children but in the event that you really want to use horizontal balusters than you must not exceed 100mm in between each baluster.
I hope i was able to provide you with enough insight.
If the handrail is officially classified as a handrail (ie, its on a stair or balcony), then the handrails/guard must be designed to prevent climbing. If the railing does not officially need to be a rail, then there is more lenience.
Where it can be proved that the design does not encourage climbing, or if there is no hazard you may get some leeway from the building inspector. Unconventional handrail design often gets you in trouble with the inspectors.
Let me know if there is anything more assistance you need.
Thank you all for your responss, I appreciate it.
