I've been on hormones for 10 yrs and post-op for 8 yrs. I live in Canada too.
Breast growth has been especially good as of late, in the last couple of years. In my case, what helped was first increasing my oral estrogen (taken first orally, then later sublingually) and then adding some progesterone. Then, switching to injections made things better on some level, skin and hair got softer, I felt better in general, all others things remaining equal more or less. Progesterone really did a number on my breasts as did higher doses of oral estrogen and injectables.
I was on Androcur pre-op and got pretty good breast growth too. But, I also took bicalutamide near the end, some progesterone here and there, finasteride and estrogen, always sublingually. Post-op, for several years, my breasts had shrunken and there was very little going on.

Like I said, it's really only in the last couple of years that things REALLY resumed.
This is my situation so I think there's still hope for you. I'm still not quite 100% satisfied with breast shape and volume but slowly getting there.
By the way, Androcur is a progestogen so exerts progestative actions on the body, similar to progesterone BUT they also differ in many ways, side-effects and all. Just thought you should know.
