Fastest Growing and Shrinking Cities

 This map shows the fastest growing and shrinking cities in the United States and Canada using 2023 data.

The map appears on Visual Capitalist and the data is only for the city populations, it does not reflect the overall metropolitan areas. The top seven population gainers are all in Canada, while all of the population losers are in the United States. 

The article does mention that if the metro areas were included, Toronto and other Canadian cities would still top the list but there is little other discussion. I suspect there is a bit of a cultural difference in the desirability of city vs suburb between the two countries and that looking at the metropolitan areas as a whole would balance out the numbers to an extent. Another factor for this specific time period (July, 2022 - July, 2023) could be that there was a temporary rise in crime in United States cities which has since abated.
