Look like a server issue

Access to fetch at 'https://geoappext.nrcan.gc.ca/arcgis/services/GSCA/multibeam_west_e/MapServer/WMSServer?f=json&request=GetCapabilities&service=WMS' from origin 'https://jsapi.maps.arcgis.com' has been blocked by CORS policy: The 'Access-Control-Allow-Origin' header contains multiple values 'https://jsapi.maps.arcgis.com, *', but only one is allowed. Have the server send the header with a valid value, or, if an opaque response serves your needs, set the request's mode to 'no-cors' to fetch the resource with CORS disabled.
