Yes there is a tax treaty. I have UK clients, I just issue an invoice and they pay it. Whether you do it via a corporation or not doesn't really matter, it's where the work is performed that counts.
The tax treaty provisions are actually easier to do in the UK, you need this form:
http://www.hmrc.gov.uk/cnr/form_canada.htm At least for basic income tax, when it comes to the other blizzard of taxes there is a separate form for each (e.g. R105 for stopping withholding on a UK bank account).
Most people don't do tax returns in the UK, it's all done automatically by HMRC. If you're self-employed then you have to do a tax return and of course corporations have to.
If you're just invoicing people and then paying yourself in Canada, really all you need is the tax treaty claim. Check with HMRC non-residents dept. though.
If you establish residential ties in the UK then you have to claim the tax treaty exemption obviously.
I can't comment on the immigration issues that come up, what I've been told by HMRC is that if you engage in visits with clients or training for up to two weeks, they don't consider that to be "working" in the UK. That comes from case law.
Residential ties are the same as under Canadian tax law, i.e. physically present for more than 90 days, or you have other significant ties such as a driving licence, etc.
