Students from Lake St. Martin First Nation are all back under one roof for classes.

The children returned to classes at a school on Ness Avenue in Winnipeg Tuesday morning. Two weeks ago, the space was shut down after it failed a city inspection.

Some of the children were moved to different public schools -- a move that has upset the Assembly of Manitoba Chiefs.

The students were supposed to return Monday, but a permit issue meant the school couldn't re-open until Nov. 20.

AMC Grand Chief Derek Nepinak says there are plans to make up the missed school days.

Almost 70 of the students were forced from their home community after flooding hit the Lake St. Martin area in 2011.
