Welcome to the community!
Judging by the specifications listed on the OnePlus Canada website here,
FDD LTE: Band 1/2/3/4/5/7/8/12/17/18/19/20/25/26/28/29/30/66
TDD-LTE: Band 34/38/39/40/41
TD-SCDMA: Band 34/39
UMTS(WCDMA): Band 1/2/4/5/8
GSM: 850/900/1800/1900 MHz
that device would have all of the compatible bands/frequencies. You can verify the compatible bands/frequencies here. You should note that there may be other versions of that phone with slightly different specifications.
**edit** The OnePlus Canada website does show Rogers as a compatible network for that device. Fido uses Rogers' networks**
Hope this helps
