Well for a start there is no such thing as Breitling in Toronto - it's a Breitling approved watchmaker that is owned by the same company that owns La Swiss, and it's for modern watches. Breitling today is a different company than Breitling from the 1960s and you can do better than having them do the work.
The only difficuly part is going to be the sliderule, we have a member here chronodeco (Craig) who can do the restoration - he'll need to see some pictures but should be able to help and will do a great job. He may have sources for the sliderule, or other members may have some thoughts, but the total cost should be less than $1,500.
If it does have to go through a Breitling source then I would use Mark Heist at Horological Services in PA. Using a US based restorer isn't a problem, you'll only pay import duty / taxes on the cost of the service, not on the value of the watch.
