This may be a less expensive source for what is called the "DanMarc valve" it is actually manufactured by a company called Advanced Fuel Components (US Company)and is a model 111. Google search comes up with a variety of sources including Amazon Canada but it is shown as currently unavailable. There is a Canadian company called National Energy Equipment with multiple locations across Canada that lists the valve in their catalog.

https://www.nee.ca/en/I have ordered and received the valve from DanMarc and in retrospect did the specific search. The shipping costs from DanMarc were more than the actual cost of the valve and it took over 3 weeks for delivery. Using the Google search "Advanced Fuel Controls 111 Canada" will give a variety of responses from both Canadian and US sources that may be less expensive and faster.
EDIT - I just checked through their store in Nanaimo and they have lots in Port Coquitlam at a cost of $41.50 CDN. the DanMarc supply cost me about $85USD with the shipping.
