This is really an extension of the Canada - Europe fare already posted ZNN72SDD and ZNN72SDU but CPT and JNB were not mentioned.
Travel from now to Mar10. Ticketing by NOV3 (but could be extended which is common with AF/KL fares like these).
There are not a lot of dates that have single connection (AMS/CDG) space in Z. But if you get creative with the free stopover in AMS/CDG, you can find quite a few dates. Easiest way to find is use a combination of EF and ITA, then use the multicity booking on airfrance.com.
Routing table for the AF/KL version is city pair based. DL version is MPM based so you will find different routings. DL version you can maximize MQM earning for final MQM run before MQM's are retired at end of year. Was able to find some in ITA with 8 segments from YYZ. (ie. YYZ-ATL-AMS-CDG-JNB-AMS-CDG-ATL-YYZ). Very hard to get to book on DL.com though...may need to call in. If flown before Dec 31 and you can book on all AF/KL flight numbers using 8 segments, then earnings would be MQM 31430 / MQD $7882 / RDM 63k-ish for Diamonds.

For Flying Blue, it can be an incredible XP trip. I found YYZ-DTW-CDG-AMS-JNB-CDG-AMS-JFK-YYZ for a total of 192 XP!!
qualifyingmiles.com | Frequent Flyer Mile and Elite Status Calculator Ended up booking with 6 segments for 162 XP that fit my schedule better. Its hard to get the 8 segment trips to price on airfrance.com with multicity tool since you only can enter 4 city pairs, but made it a game and did find a few. AF/KL version routing code basically allows DTW, JFK, AMS, CDG as connection points. MSP and ATL are not included.
Lastly, there is an I fare version for about C$300ish more each way. Lots more I inventory available.
