Flood risk accompanies spring's arrival for these provinces Jaclyn Whittal mercredi, 20 mars 2019 à 14:34 - Spring has arrived and so have warmer temperatures. Snow is beginning to melt, rivers are starting to rush and the threat for flooding is here in Canada. Residents across southern Ontario have already been dealing with early season flooding along the Humber River through the Caledon area after snowmelt, ice jams and rain caused rivers to burst their banks last Friday. Some 200 residents were forced to evacuate temporarily, but drier and cooler weather conditions have since allowed floodwaters to recede and evacuees are now home. While the area will be monitored for more flooding through the season, below is a look at what other parts of the country are also at risk for spring flooding.
