[1] A prominent figure in the founding of LWIUC was A. T. Hill, a former wobblie and the leader of the Finnish section of the Communist Party of Canada.
[3] LWIUC began publishing the monthly magazine Metsätyöläinen ('The Forest Worker') in December 1925, and it became an important mouthpiece of the Finnish-Canadian leftwing.
[3] In 1929 LWIUC sent out two organizers, Viljo Rosvall and John Voutilainen to Onion Lake to mobilize union activity amongst workers at the Pigeon Timber Company.
The company was managed by the subcontractor Pappi ('Reverend') Leonard Mäki, who opposed union organizing and had a conscious policy of mainly recruiting White Finns.
However, successful strike actions were almost impossible to organize in northern Ontario until the logging industry had recovered in around 1933.
Through these efforts the membership of LWIUC was broadened significantly, gaining a strong presence amongst Swedes, Slavs, English- and French-speaking Canadians and other groups.
