Teranet says prices were up 0.5 per cent from March, and although the gain "might appear robust" compared to the previous month, home prices always climb in the spring season.
In fact, it noted that April's increase was the third lowest for any April besides during the recession in 15 years.
Year-over-year, national home prices rose by 4.9 per cent.
Teranet says prices were up in nine cities last month, with Calgary hitting a new high, rising by 1.5 per cent.
Home prices in the Ottawa-Gatineau region also snapped out of seven months of declines, by rising by 0.7 per cent in April. While Vancouver hit a new high by jumping 0.5 per cent, following 12 months of advances.
Only two cities saw declines last month. Prices in Quebec City fell 0.5 per cent, while prices in Victoria dropped by 1 per cent.
