Tried that and NRCan was still happy, but OPUS wasn't:

FILE: n8ur_f9p_gpsrinex_new.obs OP1588779287056

 1008   NOTE: You provided a zero or negative antenna height.
 1008   If ARP HGT = 0.0, OPUS solves for the position of your selected
antenna's reference point (ARP).
 1008   If ARP HGT < 0.0, OPUS solves for a location inside or above the
antenna
 1008
 1020   OPUS aborted on the submitted data file for one or more of the
following
 1020   reasons.  OPUS cannot process the data file.
 1020   1. Collection interval of the data file was not one of the
allowed rates.
 1020      The intervals that are accepted are 1,2,3,5,10,15,30 seconds.
 1020   2. The time of each epoch is offset from one of the above
intervals.  The
 1020      seconds epoch field must coincide with one of the above rates.
 1020   3. The data file may have been collected in kinematic mode.
OPUS does not
 1020      process kinematic data files.
 1020   4. Note: OPUS processes data every 30 seconds, and 2+ hour files
 1020      collected at the 1 second rate should be changed to 30 seconds.
 1020   5. If your data were collected today or yesterday, we may not have
 1020      sufficient CORS data - try resubmitting your file tomorrow.
