1. Only one visit of one week is stated in the invitation.
The invitation letter must state the 24/7 contact information of the person you are visiting.
Evidence that your employer will be paying for your visit, not just statements/explanations.
3. It is also stated in the invitation. But I can ask my employer to write a letter where he says the same.
Have you yourself interacted with this Canadian business partner? You need to include 1-2 evidence for it (emails, for example)
Again, letters/explanations will work only if backed by evidence.
Copies of your Long Term Visa, Residence Permit, Work Permit, Medical Insurance, etc
5. Maybe a statement of property ownership? And a copy of the contract with my employer?
Copies of your property ownership documents, not just the statement + indicative market value of the property (self valuation or by a property assessor) + property tax receipts/local council taxes, etc.
I intend to submit the following documents:
1. Invitation from business partner where all required information is stated - about them, me, dates, reasons and description of activities.
Okay.
Also, any business partnership agreements + prints of the Canadian host company's web pages + some evidence to show your employer/company has had business interactions with the Canadian business partner.
2. Flights and hotel bookings
Provisional, not paid for until the visa is issued.
Also, company bank statement (your employer's) + company registration in NL + if you have been issued credit cards for business purposes.

Okay.
6. Translated to English statement that I have an apartment in the Netherlands

Is it comprehensive enough?
Do I need financial statements from my bank account?
Yes, you must include your personal bank statement (no large last minute deposits/transfers.... if any, these must be explained and the source of those deposits must match your income).
Other evidence (if applicable) to demonstrate your ties to both NL and Russia:
Financial investments + any property/land ownership + dependent family members (if you are married/have children or your parents are dependent on you) + any other work or personal commitments you must return to after your intended visit.
A Travel History explanation for the last 10 years: Visa details + entry/exit dates for each visit + purpose of each visit + scan any valid visas.
