Question about import ratio

Is there a specific number of NON-IMPORT (Canadian) players per team
that is REQUIRED to be on the field for each play in a CFL game?

Thanks

No.
There must be 20 NIs on the game day roster and 7 canucks must be starters (kickers and QBs do not count), but that can be on either side of the ball. So theoretically, if a team wants to, they could have ZERO NIs on the field while their defence is out there, and 7 starters on offence. Or vice versus.

Its law of the land too do that?I'M shocked

No dummyohiobro, its a LEAGUE rule...
