Using local macro algae (BC) in a refugium?

I agree. I would test it out in its own (separate) tank first to see if it survives reef temperatures and/or releases anything into the water. If you just added it into your fuge and it melts, your nutrient load would jump and you may be adding toxins to your display. Much better to play it safe if you're going to attempt it. Most of our macroalgaes have evolved for cold water survival, and even the tide pool varieties are adapted for that (only a short warm period around here).
