Those are two of our most populous provinces.

But Quebec has twice the population of Alberta, and it's trucking on with only 36 cases in the entire province.

The answer is that it's the Mennonites, who are overwhelmingly settled in those two provinces.

I'll be focusing on the outbreak in Ontario, because that's the part of the story I'm more familiar with.

If you dig into older news pieces, the Mennonite connection is corroborated by government officials.

Previously, Moore, the chief medical officer for Ontario, shared that this outbreak in Ontario was traced back to a Mennonite wedding in New Brunswick and is spreading primarily in Mennonite and Amish communities where vaccination rates lag.

The vast majority of those cases are in southwestern Ontario.

Mennonites have a social structure where, once the community reaches a certain number of families, they undergo mitosis, and half the families split off to form a new community far away.

Based on Reddit's scuttlebutt, it seems like there has recently been a daughter community that moved from southern Ontario to New Brunswick, which makes it doubly unsurprising that there were many southern Ontario attendees to the original Superspreader event.

Additionally, Moore, remarked in a memo he sent out to local health bodies.

Over 90% of cases in Ontario linked to this outbreak are among unimmunised individuals.

And Global News reports.

in an April interview with the Canadian press, Moore reasserted that the vast majority of Ontario's cases are among people in Mennonite, Amish, and other Anabaptist communities.

Some smaller publications have found connections in their own investigation.

The London, Ontario, Free Press in March 2025, the beginning of the outbreak, linked the outbreak in West Texas to their Mennonite population, and identified that several measles exposure sites in counties that have been heavily afflicted by measles are Mennonite in nature.
