In my opinion, the following Ontario law, the Health Care Consent Act, should apply to the “vaccine”, the testing, the masking, the social distancing, and the screening. I have highlighted sections of it.

“treatment” means anything that is done for a therapeutic, preventive, palliative, diagnostic, cosmetic or other health-related purpose, and includes a course of treatment, plan of treatment or community treatment plan, but does not include,
. . .
[etc.]
. . .

Part II
TREATMENT
General

. . .

No treatment without consent

10 (1) A health practitioner who proposes a treatment for a person shall not administer the treatment, and shall take reasonable steps to ensure that it is not administered, unless,

(a) he or she is of the opinion that the person is capable with respect to the treatment, and the person has given consent; or

(b) he or she is of the opinion that the person is incapable with respect to the treatment, and the person’s substitute decision-maker has given consent on the person’s behalf in accordance with this Act. 1996, c. 2, Sched. A, s. 10 (1).

. . .

Elements of consent

11 (1) The following are the elements required for consent to treatment:

1. The consent must relate to the treatment.

2. The consent must be informed.

3. The consent must be given voluntarily.

4. The consent must not be obtained through misrepresentation or fraud. 1996, c. 2, Sched. A, s. 11 (1).

Informed consent

(2) A consent to treatment is informed if, before giving it,

(a) the person received the information about the matters set out in subsection (3) that a reasonable person in the same circumstances would require in order to make a decision about the treatment; and

(b) the person received responses to his or her requests for additional information about those matters. 1996, c. 2, Sched. A, s. 11 (2).

(b) by the person’s substitute decision-maker, if the person is incapable with respect to the treatment at the time of the withdrawal. 1996, c. 2, Sched. A, s. 14.

. . .

I am not sure about how the enforcement of all of these sections work. There is a reference to the Provincial Offences Act. Search the words “guilty,” “penalty,” “offence,” “contravenes.”

Provincial Offences Act, RSO 1990, c P.33

General

Purpose of Act
2 (1) The purpose of this Act is to replace the summary conviction procedure for the prosecution of provincial offences, including the provisions adopted by reference to the Criminal Code (Canada), with a procedure that reflects the distinction between provincial offences and criminal offences.
