Passage: If Day was an elaborate campaign to promote the purchase of Victory Bonds. These bonds, which were loans to the government to allow for increased war spending, were sold to individuals and corporations throughout Canada.  If Day was the second Victory Loan campaign of the Second World War. The campaign began on 16 February 1942, and continued until 9 March. Manitoba's fundraising target was $45 million ($620 million in 2011 dollars), including $24.5 million from Winnipeg. The Greater Winnipeg Victory Loan committee, a regional branch of the National War Finance Committee, organized If Day under chairman John Draper Perrin. The organizers believed that bringing the war (or, rather, a simulation thereof) to people's homes would result in a change of attitude among those not directly affected by the war.The committee drew up a map of Manitoba, which was divided into 45 sections, each representing $1 million of their fundraising target. As money came in from those selling Victory Bonds, the sections were "reclaimed" from the Nazi invaders. The map was posted at the corner of Portage and Main, the city's central intersection. The campaign was publicized in local newspapers for a few days before the event, although the "invasion" took many citizens by surprise. To prevent a rush to emergency shelters, residents of neighbouring northern Minnesota were also warned because radio broadcasts dramatizing the event could be received in that area. Royal Canadian Air Force aircraft painted to look like German fighter planes flew over the city on 18 February 1942. Selkirk, a small town northeast of Winnipeg, held its own fundraising simulation, a one-hour blackout and mock bombing, on 18 February 1942 in preparation for the main If Day event.
