The retailer said Tuesday it earned $818,000 or a penny per diluted share for the quarter ended March 31, down from a profit of $5.4 million or seven cents per diluted share a year ago.
The drop came as same-store sales fell 3.8 per cent compared with a year ago.
"The profit decrease in the quarter was related to lower same-store sales, partially due to the extreme weather conditions across Canada," the company said in a statement.
"Further, gross margin dollars could have been higher had we reacted more quickly to the decline in the Canadian dollar. Finally, finance costs and non-cash purchase price adjustments related to the acquisition of The Brick further lowered profit."
Revenue totalled $426 million, up from $162 million, boosted by the acquisition of The Brick chain of stores that closed near the end of March last year.
Total system-wide sales were $508.4 million, including $82.4 million of franchise sales in the quarter, up from $203.6 million, including $41.1 million in the first three months of 2013.
