Is the Canadian online advertising market finally showing signs of dynamic growth? According to the Interactive Advertising Bureau of Canada, the market grew 54% last year to C$562-million from $519-million $364-million in 2004. Before anyone gets too excited, it is important to remember the U.S. online advertising market last year was $12.5-billion so Canada is nowhere close at the traditional 10:1 ratio used when comparing the two markets and their respective populations.
