Hi, I have a large (about 20 years old) Jasmine Officinale. It has been robust and needed very little care over the years. This year it appears to be dying. Over the past month I have noticed the leaves all turning brown. We have had sufficient rain and lots of warm weather. I live in Victoria, BC. Do these plants have natural lifespan?

Jasmine officinale are known to be quite disease and pest resistant. They also can live hundreds of years with proper care and unharmed from environmental issues. Inspect your vine for any other marks on the leaves or to see if pests are present. Some insects can be difficult to see with the naked eye.
Pruning can help the vine by opening it up to air circulation. This can help reduce the risk of fungus infections. Make sure the soil is well draining and that the ground is not holding too much water. You could treat the plant with Neem Oil. Neem Oil is organic and safe for people, pets and bees. It also works as both an insecticide and fungicide. This treatment can't hurt the plant and may help.
