Here, it's the opposite. Finding a 10w-40 synthetic usually requires a niche market (i.e. Mobil 1's 10w-40 motorcycle oil) or a niche product altogether, like RP 10w-40. I don't think I've ever seen an A3/B4 10w-40 in the wild here.
As SonofJoe indicates, it's something I would avoid. General Motors was always beating the drum against that grade, too, for a lot of years. I don't think we even have any A3/B4 blends here, except perhaps some specifically imported. All our A3/B4 stuff pretty much 0w-30, 5w30, 0w-40, and 5w-40, marketed as synthetics. I'd probably consider a boutique 10w-40 to be "fairly close" to an A3/B4 and be a fairly suitable oil, but when the A3/B4 options from the majors are available at half the price, and a conventional 15w40 E7, E9 cheaper still, there's not a lot of incentive for me to grab a 10w-40.
As I hinted at above, Imperial Oil (our Exxon-Mobil) only has one 40 grade product outside of HDEOs, and that's the 10w-40 motorcycle oil. They don't even make a 10w-40 PCMO for this market. Shell has a couple examples. Castrol makes a 10w-40, but their rule in Canada is that if a grade is possible, they'll have it on the shelf somewhere.
+1 with Garak. 10w-40 isn't common in Canada.
Even 10w30 is hard to find on some brands of oil. Most common weights are 5w-20 and 5w30.
I'd you need other weights they are available, but usually don't go on sale as often and cost a bit more.
If you go to Walmart in the US, it's like you are in oil heaven. Most brands especially Mobil 1 are readily available in every weight.
