And the Anglican Church is vigorously promoting it, so is the Evangelical Lutheran Church in Canada:

Back to Church Sunday (B2CS) is the largest single local-church invitational initiative in the world. It is based on the simplest and shortest step in evangelism – that we should invite someone we already know to some-thing we love – inviting a friend to our church.

[….]

In Canada, the Anglican Church of Canada has been part of the B2CS initiative for two years. Last year, hundreds of Anglican congregations in Canada contributed to the more than 80,000 people globally that came back to church for B2CS. This year, the Evangelical Lutheran Church in Canada is joining the initiative, as are congregations from other Christian traditions.

The week after, both churches will hold services of repentance for Back to Christ Sunday.

Actually, they won’t, that was just my fevered imagination working overtime.
