% of workforce that commutes to Winnipeg in surrounding municipalities 2016 census.

1. West St. Paul 86.2%
2. East St. Paul 84.0%
3. Headingley 77.7%
4. MacDonald 75.9%
5. Ritchot 74.2%
6. Rosser 73.6%
7. St. Francois-Xavier 72.2%
8. Springfield 70.8%
9. Tache 65.4%
10. St. Clements 58.3%
11. Niverville 55.8%
12. Woodlands 54.1%
13. St. Andrews 53.4%
14. Stonewall 50.4%
15. Rockwood 49.7%
16. Cartier 49.7%
17. Brokenhead 36.8%

So it looks like Niverville, Woodlands and St. Andrews have met the threshold to be included in the CMA (from what I understand). If St. Andrews is included, Selkirk may be as well so there isn't a "hole" in the CMA.
By 2021, Rockwood and Cartier will likely exceed 50%, which would also see the inclusion of Stonewall and Teulon into the CMA.
It's possible that by 2026, the entire capital region (minus Brokenhead) and Woodlands will be part of the CMA.
