The following is directly from Belleview Golf:

UPDATE: The golf course will be closed for 2 weeks starting tomorrow due to the new regulations set forth by the province of Ontario. As a business we have implemented many safety measures and will continue to do so even once we are able to re-open. I would like to remind everyone that there have been many years where the golf course hasn’t opened until mid-April or even May. So if restrictions continue past the next two weeks it is not the end of the world.
The most important thing going forward is that we as a country and community follow the protocols set forth by the government and public health officials. Not only will this help save lives, but it will also help us get back to normal (a.k.a. GOLFING!) sooner than later.
Everyone stay safe and we hope to see you all again in a couple weeks!
