I am getting the following message when transforming any dataset between EPSG 3347 and EPSG 4326.
Warning 1: Several coordinate operations have been used to transform layer lda_000a21a_e. Artifacts may appear.
You may consider using the -ct_opt ALLOW_BALLPARK=NO and/or -ct_opt ONLY_BEST=YES warping options,
or specify a particular coordinate operation with -ct. This warning can be silenced with
-ct_opt WARN_ABOUT_DIFFERENT_COORD_OP=NO.
