There are lots of questions regarding the newest changes to the maximum number of people at a worship service in the Re-Open Saskatchewan Guidelines. The updated guidelines state:

Delivering services virtually or through remote delivery such as drive-in service is recommended.
The total number of people participating in the services cannot exceed 30 per cent of seating capacity or 150 people, whichever is less.
To safely support larger groupings of individuals – and where seating area allows adequate physical distancing of two metres between individuals or family units – multiple groups of 30 are permitted. These groups must be separated by five metres.
