Tango flights are eligible for 100% credit when flying outside of NAmerica. However, the segments within Canada (YEG-YYZ) would be 25% non-status

The good news is that I find international Tango fares are prices at 5-6 times Tango+ fares...so I'm 99% sure you'll be booked into Tango+. Just make sure to get the TA to book on AC metal, since the AC codeshare on LH will likely give 50%.
