I have decided to go with Shell Rotella SB oil. As far as I can tell it exceeds all of the desired specs and then some, including the CH-4 requirement. Price in Ontario is about $3.50Cdn/Litre, and is available in 20L pails.
For supplies from Shell, this link should list the Ontario Canada dealers:

You can work backwards from there for other Canadian suppliers. I was told "about a week" for "special orders". The product I ordered is the 10W-40 Synth Blend. They do make a 0W-40 full synth, but this is $5.60/L, and would only be useful I think if we were going for long drain intervals.
Although it would be nice to so do, I feel SB is a good compromise, and it is also fine for my gasoline vehicle.
PS: I found that the Shell distributor went by product name - not the number shown on the Web-site
