During
World War II, on a trans-
Atlantic crossing, Acorn suffered a wound from depth charges. The wound was severe enough for him to receive a disability pension from Veterans Affairs for most of his life. He returned to Prince Edward Island and moved to
Montreal, Quebec, in 1956 and was for a time a member of the
Labor-Progressive Party. He spent several years living at the
Hotel Waverly in
Toronto, Ontario. In Montreal, he published some of his early poems in the political magazine,
New Frontiers. In 1956, he self-published a mimeographed chapbook,
In Love and Anger, his first collection of poems. In the 1950s, some of his poetry was published in the magazine
Canadian Forum. He was for a short time married to poet
Gwendolyn MacEwen. In the mid-1960s, he moved to
Vancouver and joined the
League for Socialist Action. In 1967, Acorn helped found the "underground" newspaper
The Georgia Straight in Vancouver, British Columbia. In 1969, he published his poetry collection ''I've Tasted My Blood''. Acorn was awarded the
Canadian Poets Award in 1970 and the
Governor General's Award in 1976 for his collection of poems,
The Island Means Minago. In 1977, Acorn introduced the Jackpine sonnet, a form designed to be as irregular and spikey (and Canadian) as a
jack pine tree, but with internal structure and integrity. Without a fixed number of lines and with varied line lengths, the Jackpine sonnet depends on interweaving
internal rhymes,
assonance and occasional end-
rhymes. In July 1986, he suffered a heart attack and was admitted to the hospital. Acorn died in his home town of Charlottetown on August 20, 1986, due to complications associated with his heart condition and diabetes. According to fellow poet and friend
Jim Deahl, he had "lost his will to live after the death of a younger sister." ==Milton Acorn People's Poetry Award==
