This is exactly the point I was going to post. Unconscious patients can't refuse treatment (without a substitute decision maker).

Just a couple of add on points. I am not a doctor or a lawyer, but I would highly doubt that a med-alert bracelet saying "do not transport to hospital" would get followed. Even if a patient says "don't transport me" to a paramedic's face, then goes unconscious their request wouldn't be follow. The reason is that implied consent errs on the side of life. Yes, the patient my have made an informed decision before going unconscious. However, as of going unconscious their circumstance and status has changed, and since they cannot interpret the new information to make an informed decision, implied consent takes over. Also consider if it did work, but OP did need hospitalization this time. If the paramedics couldn't move him/her that would really suck.

Instead I would recommend OP follows this up with their Family care doctor (or even a walk in). If there is a known cause that's not dangerous I would recommend OP spend his/her time informing their colleagues, or whoever else is calling 911. This is the same tactic that epileptics have to use. Many epileptics have multiple seizures per day, and if they went to the hospital for every one, they'd be broke.

Lastly, Ontario doesn't have EMTs. We have paramedics. Different level of training.
