YYZ-BOG (A330 widebody signature service, with AC pods) has tons of days this summer with Aeroplan avail, 6 to 9+ J. Reasonable points cost 48,500-49,900. Includes International Maple Leaf Lounge access.
You can probably get further than BOG but the onward connection on Avianca will likely be economy (they are eliminating business class)
