It's certainly been the pattern in a lot of the ethnic communities. For example, a lot of those who came here in the wake of World War II had a diversity of publications, and were fairly strong in those early years.
As people become more and more integrated into the Canadian population over time, the population gets older, and the subsequent generations get less attached to the community. You see closures and consolidations and mergers, with fewer and fewer publications, and less frequency.
Is that a pattern you see, or has the wave of recent post-1991 immigration helped stave that off a bit?
