IIRC it's the "tube" or "underground" that connects T3 - T4 and the HEX that connects T3 - T5.
You'll pass through immigration when you get to T3, take the Tube to T4, then on return take the Tube to T3, connect immediately to the HEX to T5 and then go through the regular departures in T5 as though you were originating in the UK. Hopefully you'll get the boarding pass from LHR to your final destination in Canada.

Unless it is the rule to retrieve and re-check-in the luggage at Heathrow for all international flights (as was what I have experienced at Chicago airport) anyway..?
If your baggage has been checked to your final destination it won't be put onto the carousel and you wait see it in London.
