Not in Vancouver per se but...
I don't know this 100% for sure but I do understand that the Aoyama Cafe inside Aberdeen Centre in Richmond has Blue Mountain. They are on the lower level in front of the water fountain. They brew to order using the syphon method however I have never tried their Blue Mountain coffee.
There is also a small coffee shop called
La Cuisson in the same complex as Richmond Sushi and Yavis Club which serves Blue Mountain. I have been there before and the owner there is a serious coffee guy. He brews his coffee using Hario syphons which I've tried myself. The owner brews to order and you can watch him practice his meticulous skill as he prepares the coffee for you. He uses the Hario syphons which is far more superior than the competition out there. I understand that the owner also buys fresh green beans and roasts in-house to assure you get the freshest and highest quality coffee. If that doesn't sound tempting, he can also pull a mean espresso using his Nuova Simonelli Oscar machine. Definitely worth a try however, be forwarned that English
may be a challenge.
Edit:
Viva Java on Cambie in Richmond sells certified Blue Mountain beans however I don't know if they serve it.
