OP, why do you ask? If it is to have a non-restricted rifle with an AR upper then be aware that the RCMP will do anything necessary to make sure it isn't classified as such.

Any lower than can bolt onto a unmodified AR upper will be classified as variant thus remained as a restricted.
Another travesty was perpetrated on Alberta Tactical Rifle when they built a special AR lower to work with a single shot .50BMG upper they made. Their goal was to have a non-restricted single shot long range rifle that used AR lower parts (grip, FCG) for a common feel and easy accesorization. From what I have read, ATRS went so far as to not machine a mag well in the lower and incorporated other changes to make it not work as an AR.
Since the RCMP test on AR's is to see if an AR upper can be fired on the lower, they worked very hard to do just that, even though ATRS made a serious effort to make that impossible.
With dedication, hard work and talent the RCMP firearms lab achieved their goal of firing a standard AR upper off the ATRS lower. They did this by DUCT TAPING THE UPPER INTO PLACE AND FIRING A SINGLE SHOT WITH IT.
Result? Classified restricted and worthless to anyone wanting to shoot the single shot .50BMG outside of a range.
I have no words for the loathing I feel when presented with bureaucratic malfeasance such as this.

The RCMP DID duct tape an unmodified AR upper to our 1st submission and managed to get it to fire 1 round, so deemed that version as restricted.
The latest version has been deemed a "trigger group" hence not needing registration. I am at this time trying to reason with them to reclassify it as a non restricted firearm, as being a trigger group will only result in someone having needless legal expenses when challenged by any LE officer.
Yes, but what about the case of a lower that is already classified as non-restricted??OP, why do you ask? If it is to have a non-restricted rifle with an AR upper then be aware that the RCMP will do anything necessary to make sure it isn't classified as such.
