Local Where to buy Kansui or Food Grade Lye Water in Vancouver

I'm trying to make hand pulled noodles and I'm wondering if you can get kansui or lye water in the lower mainland? I'm in Burnaby.

 

Check your local independent Asian supermarket, they might have kansui.

Lye or caustic soda (sodium hydroxide) can be found at soap making stores though I am not certain if it's food safe. This one is located in Surrey: http://www.voyageursoapandcandle.com/Lye_Sodium_Hydroxide_p/62190.htm

If you're unable to find kansui or lye water, one substitute I've heard of is from Harold McGee: Just spread a layer of baking soda (sodium bicarbonate) on a foil-covered baking sheet and bake it at 250 to 300 degrees for an hour. It converts it into ash (sodium carbonate) which is a stronger base than unadulterated baking soda.

 

It's a haul to New West phone first-although if you like to bake it's The place for you.

The ones I've seen locally are the Koon Chun brand kansui. I got mine at Rong Hua Supermarket on 41st and Victoria Dr.

It's labelled as Koon Chun Potassium Carbonate and Sodium Bicarbonate Solution and looks like this:
