"Historically, many American anglers brought leeches into Ontario from the United States (Walther-Landon 1986). It has been estimated that 50-60% of the leeches used by anglers in Ontario originated from outside the province (Friesen 2000).This practice was discontinued in 1999 when anglers were banned from importing leeches into Ontario. By 2005 the ban had been extended to commercial operators"
Im not too sure about that ban on commercial operators, if it is meant for importers only...but the fact is, I haven't seen shops retailing them for quite long a time

上次我买到leeches是2005年的Bass开季,一条鱼没有钓上,从此再也没有用过!
