As you might know Sympatico is using DPI (deep packet inspection) to apply throttle according to the data transmitted, despite of what you might have heard, changing the port is ineffective and buying a compatible router to flash it with the tomato firmware to be able to use mlppp (Multi-link point-to-point protocol) is unnecessary and expensive.

As long as they keep using the same methods, all you need to do is use a decent torrent client like Ktorrent who gives you these kinds of options:

[X] Use encrypted protocol
[ ] Allow unencrypted connections

I noticed that if you allow unencrypted connections it does not get any better, probably because they can catch a couple of torrent packets and spot the port then apply port throttling, otherwise it could be just another online game that runs on a random port.

There is one inconvenient to this method, not everybody uses decent torrent clients, so you lose the participation of some of them. While running it encrypted only, i connected to many Azureus, Transmission, libtorrent based, they should then contain such options.
