Check up on the laws. There are other tactics you can take (which I haven't done yet) such as serving people who refuse you entry with Notices of Liability (see Action4Canada's at https://action4canada.com/covid-liability-notices/) and submitting human rights complaints. These may or may not have success but at least it will have the effect of making denial of service more of a hassle than it's worth. Also, good for you!
