If you have been absent for more than 2 years you're unlikely to qualify as a Returning Resident and definitely won't qualify for a new SET(M) application. ILR is generally lost after 2 years of absence.
You can try applying as a Returning Resident but you may well have to start from scratch and apply for a Spouse Settlement visa. This would require you to meet the financial conditions. The options for this would be:
1. Your husband returns to the UK ahead of you and after being employed for 6 months earning £18,600 p.a (pro rata), you then submit your spouse visa application from Canada
OR
2. Your husband submits evidence of earnings in Canada the equivalent of £18,600 p.a for the 12 month period prior to submitting your application AND he has a confirmed job offer in the UK to start within 3 months of arrival, again meeting the £18,600 p.a income level
OR
3. You qualify with savings of £62,500 which has been held in an accessible account for at least 6 months (unless from a sale of property, in which case the 6 month period doesn't apply).
By the way, there is no longer a 2 year route. It's now 5 years (2.5 x 2.5)
