I was just looking it up and Health Canada just approved an antibody test last week. It won't be available to the public until July at the earliest.
I agree, the quarantine think sucks, but being separated from family is hard. I cheated the last two weekends.
We celebrated Mother's day at my parents place on the 17th. We were outdoors in their backyard at two separate picnic tables. No touching and I never got closer than about ten feet from them and I brought my own food and drinks. Last weekend I went to Ottawa and spent a couple hours with my sister in the park. It was the first time I got to see my niece in person since she was born in February. Again we stayed far apart and no touching. I think we've gone overboard on keeping people apart and haven't given enough thought to mental health. If you keep it outdoors, wear a mask and stay at least two meters apart you should be allowed to see your loved ones.
