So - I contacted Millbrook LEAF program, and the case was that I did in fact jump the gun.
Steven was super helpful, there were a couple left and he processed a return / refund on the one I purchased and I got another at the sale price.
All this to say - All this credit goes to Millbrook. Your customer service is absolutely fantastic. I have never bought from you guys before, but guaranteed I will buy from you again. Definitely going to pick up some Arcteryx stuff from you before winter really digs in, you're now in my list of top businesses in the Canadian firearms, outdoors and tactical community.
